Breeding chickens is troublesome, so you need to try to make it have the most bang for your buck. The satisfactory productivity of poultry, along with other activities, is provided by the hood in the hen house.
Without the entry of clean air into a limited space, the health of the hens is at risk, therefore, egg production is reduced.
The role of ventilation in the creation of a microclimate house
In the chicken coop, as in any house, there are ammonia vapors dispersed throughout the room. If fresh air does not come in from the outside and harmful evaporation reaches a high concentration, its inhabitants begin to ache, and in some cases this becomes the cause of the case. Feathers and heat are not well tolerated, so a system that allows air to circulate is simply vital for them.
Without ventilation, it is difficult to control the humidity of the air. Birds are equally bad in both excessively wet and dry conditions.
This problem becomes especially urgent in winter, when all the livestock are constantly in a confined space. The air accumulates carbon dioxide, water vapor, plus poisonous ammonia released by the droppings. Rotting bedding and scattered food on it is a good basis for the reproduction of harmful microorganisms.
Just opening the door is not an option. This way of providing fresh air can create another problem - freezing the ridges. Dangerous temperature drops, drafts are dangerous for layers. Therefore, the presence of a competent scheme of general ventilation in the hen house in winter is a matter of urgency.
Existing ventilation methods
There are 3 ways to ventilate a room where poultry is kept:
The first is the most inexpensive and is used when there are a small number of chickens. It is a simple airing, but it must be arranged according to certain rules. Before you decide to do this ventilation in the hen house with your own hands, you need to take into account all the points while designing the birdhouse.
The second method of ventilation is more efficient, but simple to perform. If there are more than 20 birds in the farm, you should stop on this variant.
Mechanical ventilation can be inlet, exhaust or combined, i.e. forced-air and exhaust. Her suit in large farms. The feasibility of using a mechanical system and in the poultry house is determined by the size of the livestock - the room must be designed for a hundred or more chickens.
In a combined mechanical system, either the exhaust air mass is discharged naturally, and fresh air is pumped mechanically, or vice versa.
Four basic ventilation requirements
The coop ventilation system will work effectively only if the basic requirements for this room are met:
- Continuous maintenance of the house with clean air.
- No drafts, because the inhabitants of the coop are very sensitive to them.
In addition, to exclude instantaneous air pollution coming to replace the exhaust air mass, taken away from the exhaust air, it is necessary:
- Regular removal of litter, spoiled feed and dirty water.
- Periodic extermination of small rodents. In addition to the fact that their presence worries birds, they also serve as a source of additional air pollution.
To make sure that the ventilation is complete and functioning properly, go to the hen house and stay there for a while. If you do not feel a lack of air and your head does not start to hurt, then the test is passed. Otherwise, you have to fix something.
Self-made device for ventilation of the chicken coop
At arrangement of ventilation of a house hen house it is quite possible to manage by own strength. It is important to do everything correctly to ensure a comfortable environment:
- The temperature in the cold season is not lower than 16⁰ for adults and 28⁰ for chickens.
- Humidity from 60 to 80%.
- The air flow rate is 0.8 m / s maximum in the summer and not more than 0.5 m / s in winter. If these indicators are exceeded, drafts will walk inside the room.
The ventilation scheme in the hen house and in other buildings is built on the same principle. Proceed from the floor space and the number of birds. Determining the performance of the system, they take such a moment as a basis: there should be 5 chickens per square meter area.
To resolve the issue with ventilation, you need to decide on its appearance. The next step is to draw up a detailed scheme, then purchase materials. Then it remains only to follow the technology and perform the necessary work.
Natural house ventilation
It is based on the parameters of the air environment: temperature, pressure, wind speed. This type of ventilation can be both unregulated and organized. Unorganized ventilation or infiltration occurs through loose doors and windows.
For organized air circulation (aeration) a small window should be provided, positioning it in the ceiling above the perch or directly above the doorway. To control the window do in the form of vents.
The door in the open state will supply the house with fresh air, and through the window it will leave the waste. Good this way for the warm season. In winter, the effect of such ventilation is negligible. It is unprofitable, because leaves a lot of heat. You will have to spend a lot of money on maintaining the optimum temperature inside the house.
We make the exhaust ventilation themselves
The most primitive circulation or open-loop system, suitable for a room of about 9 m², consists of 2 sewer pipes 2 m long each, with a cross section of 200 mm and a 90 ° bend. One of the pipes will act as an exhaust. It is mounted above the roost at or above the ceiling. To rise above the roof, it should be 1-15 m. To do this, make a hole of the appropriate size, insert the pipe and the knee, blow the slots with mounting foam.
On the opposite side, using the same method, install the second pipe, positioning it 0.5 m below the first level, 20-25 centimeters should remain to the floor. In order not to provoke drafts, the intake pipe is placed away from the perch. Installation, made in accordance with regulatory requirements, implies that the opposite end of the pipe goes 0.3 m beyond the roof.
Valves must be installed on the pipes. To prevent dust and precipitation from entering the room through the pipes, their ends are made l-shaped or umbrellas are installed. You can purchase and install special nozzles - deflectors. Under the influence of wind, they increase the vacuum in the pipe. The outer side of the pipe putty and paint. This will insure against gaps in the future.
The most effective air circulation is provided by pipes with a circle in cross section. Products made of plastic and metal are better insulated, otherwise in the winter on the inner walls of condensate. By freezing, after some time it can block the ventilation path completely.
To securely fix the pipes they are installed near the rafters. In some cases, additionally secured with staples. Sometimes instead of pipes arrange channels from the boards. In this case, you need to pay special attention to their sealing.
At very low temperatures, the dampers of the air ducts overlap, and if they are not installed, protect the holes from the wind flow with a cloth. In the summer, the air ducts open completely. There is another simple ventilation method for a small chicken coop:
- A box is constructed from planks, having a cross section of 200 x 200 mm in section. Install the structure vertically.
- Divide the inside of the canal in half.
- Close the top of the box.
- Seal and color the outer surface of the channel.
- Drill holes in the sides.
The downstream side of the canal will provide air to the chicken coop. Exhaust air will escape through the second half of the duct.
If the area of the chicken coop is large, it makes more solid ventilation, acting on the supply and exhaust principle. To do this, perform preliminary miscalculations and create an individual project. It is important to choose the right cross-section of pipes so that air flows do not create drafts.
For ventilation pipes, you can purchase ready-made valves, both round and rectangular in cross section. The casing of the corresponding section and the flap is included in their design. Round valves are made of galvanized sheet products, and rectangular valves are made of sheet aluminum.
Valves with a damper, the position of which is adjusted manually, are marked with the letter P. If the model is controlled using an electric or pneumatic actuator, then the letter E or P is present in the designation, respectively. You can apply a standard round valve with a pipe diameter of 250 mm. The expediency of their use is determined by the scale of the house.
We arrange mechanical ventilation in the bird house
The task of mechanical exhaust is to provide the optimum mode regardless of the weather. On a small-scale farm, its use does not always justify the costs associated with paying for electricity. It is impossible to recoup the costs if chickens are raised only for the needs of the family.
This type of ventilation is similar to the supply-and-exhaust method, but here a slightly improved technology is applied, consisting in the use of fans. In some cases, the system is operated in manual mode, in others - there are special control panels.
In the scheme of mechanical ventilation for use in winter there are two pipes and a fan, the location of which depends on the type of circulation. To ensure the ventilation it is placed in the intake pipe. At the device of an effective exhaust fan should be in the exhaust pipe. The installation process is almost the same as with the device for supply and exhaust ventilation:
- Install 2 pipes.
- Drill holes for condensate at the end of the chimney.
- Lay the wiring to the place of installation of the fan.
- Mount the switch. There can be 2 options: a switch that turns on the light and the hood at the same time or a 2-key switch that allows you to control the lighting and the hood separately.
- Install the fan.
In a simplified version of the mechanical retractor fan is placed in the wall on the ceiling or in the window window. The last option is the easiest. Fan try on, cut to the size of the glass rectangle of OSB or plywood.
Mark and cut out the opening for the fan, then insert the element into the frame and fix the screws. The fan itself is inserted into the hole. The method of fixing the latter depends on its design.
Connect the fan included in the system to the electrical network. Wiring is better to lay outside the coop, because inside for this condition is not quite suitable. It is important to insulate the wiring carefully. Such ventilation is not necessary to leave in working condition for a long time. It can work only 2-3 hours per day and this will be enough for effective ventilation.
For ease of management install sensors. At a certain humidity and temperature, they enable and disable ventilation. Sometimes the pipes are placed in the attic and the fan in the ceiling.
Deflector for ventilation pipe do it yourself
Install it on the roof. The deflector works as follows: it cuts the wind directed in its direction, which leads to a decrease in pressure inside the device and an increase in thrust in the exhaust duct.
Independent production of a wind turbine will be inexpensive, and the effect is impressive. Install it on the roof. Before proceeding to its manufacture, you need to calculate the dimensions. To calculate the height, the diameter of the ventilation pipe is multiplied by 1.7. By multiplying the diameter by 1.8, the cap width is obtained, and when multiplying this parameter by 1.3, the required width of the diffuser is recognized.
Having calculated the sizes, they are put on a cardboard and cut out patterns. Next, scan the cap, the sketches of the workpieces of the diffuser, cylinder and racks are transferred to a metal sheet or plastic. With the help of scissors cut out all the details and connect them using a special gun. It remains to install and secure the deflector.
You can also make a butterfly valve yourself. For this, a frame is welded from the corners. On opposite sides of the frame, drill holes and thread an axis into them. Bushes are made from pipe sections, welded.
The steel plate is used to make the locking plate according to the pipe size. It is inserted into the frame, fixed to the axis by welding. To control the valve on the axis of the fix wooden handle. To prevent the flap from closing spontaneously, a limiter is provided.
The disadvantage of such a ventilation system is the fact of the presence of pipes in the room. From their surface, as well as from the perch, will have to periodically scrape the litter.
Conclusions and useful video on the topic
You will learn about the importance of ventilation in the house from this material:
Any business can be mastered if you carefully follow the instructions. Do the drawing in your own henhouse with your own hands and your birds will feel much better.
In the chicken coop, as in every poultry house, there are ammonia vapors that are dispersed around the perimeter of the room. If there is no access to clean air from the outside, and toxic fumes are high in content, then chickens can start to get sick often, and in some situations this is the cause of massive mortality. Also, birds do not tolerate high temperatures, because the correct installation of the ventilation system, which would allow air to circulate normally, is vital.
Without ventilation, it is difficult to regulate the air humidity. Birds are equally uncomfortable in both very dry and very wet coops. This issue becomes even more relevant in the winter when all the birds are always in a closed room. The air accumulates water vapor, carbon dioxide and ammonia emissions, which are formed from litter. The rotting substrate on the floor and the food on it is the ideal basis for the development of pathogens.
Just leaving the door open is not the way out. This option of providing clean air may cause another serious problem - freezing of scallops. For chickens there is a danger of drafts and sudden changes in temperature. Therefore, it is correct to make ventilation in the hen house a very topical issue for any poultry farmer.
There are three main ways of ventilation of the chicken coop: mechanical, forced and natural.
Natural ventilation - This is the most economically financially way, which is used when maintaining a small number of chickens. This option of ventilation is an ordinary airing, but it also obliges to observe some rules. Before you decide to do this ventilation in the hen house with your own hands, you must take into account all the nuances in the design of the hen house. Constructing the house, it is necessary to organize everything so that drafts do not appear. They appear in case the selected pipe section is larger than the calculated values.
The second option is more efficient, however, and in the implementation of more complex. If the house contains more than 25 chickens, then it is best to use forced ventilation.
Mechanical ventilation is usually equipped in large farms. The feasibility of using this method in a domestic chicken coop should be determined by the size of the livestock - the house should be designed for more than 100 chickens.
Selected and hand-made ventilation scheme in the barn will work effectively only if the basic rules that apply to the chicken coop are followed. Required requirements:
- Regular provision of premises with fresh air.
- The constant extermination of various rodents. Besides the fact that their presence disturbs chickens, they are also an additional source of pollution.
- Periodic removal of dirty water, rotten feed and litter.
- Lack of a rotten smell.
To make sure that the ventilation is working properly, you need to go into the house and stand for some time. If there is no feeling of lack of oxygen and not dizzy, then nothing needs to be fixed. Otherwise, you must look for the cause.
During the ventilation device in the house you can do everything yourself. The most important thing is to provide birds with comfortable conditions:
- The air velocity is not more than 0.9 m / s in summer and not higher than 0.6 m / s in winter. During the excess of the indicators in the hen house drafts appear.
- Humidity 65−85%.
- Winter temperature is at least 15 degrees for adult birds and at least 29 degrees for chickens.
The ventilation scheme is developed according to a single principle. Given the number of birds and the area of the chicken coop. When calculating the capacity of the system, the basic rule is taken as a basis: 5 chickens are required per 1 m² of room.
To solve the issue of ventilation, you must select a specific type. The next stage - the drafting of the project and the purchase of building materials.Then you only need to comply with the technology and perform the required work on the organization of ventilation.
At the heart of this ventilation system are air indicators: wind speed, pressure, temperature. This method of ventilation is organized or unregulated. Unorganized ventilation or infiltration is performed using loosely closed windows and doors.
For air circulation, it is necessary to provide a small window by placing it on the ceiling above the roost or above the door. To be able to control traction, the window is constructed in the form of vents.
The open door will begin to supply the coop with clean air, and the exhausted one will leave through the window. This option is great for the warm season. In winter, the effect of this ventilation is small. It is irrational, as it removes a large amount of heat from the room.
Open or circulation system
Supply and exhaust ventilation is suitable for a poultry house with an area of approximately 10 m². The ventilation of the chicken coop consists of plastic pipes (2 pieces of 2 m each, with a diameter of 20 cm) and an elbow of 90⁰. One pipe acts as an exhaust, it is installed above the perch under the ceiling. To go beyond the level of the roof, it is obliged to 1.2−1.7 m. For this purpose, a hole of the required diameter is performed, a pipe is installed and the gap is blown with building foam.
From the opposite side, another pipe is inserted, but 50 cm below the top of the first one, while remaining 30 cm to the floor. In order not to provoke drafts, the second pipe is installed far from the perch.
It is necessary to install dampers and an umbrella on the pipes in order to prevent the ingress of garbage and precipitation into the chicken coop.
The most effective air circulation have round tubes in cross section. It is desirable to warm plastic and metal products, otherwise in the winter condensate forms on the walls.
To firmly fix the pipes, they are placed near the rafters. Sometimes additionally fixed with staples. In some cases, instead of pipes, the channels from the planks are equipped; then great attention should be paid to sealing.
At low temperatures, the ventilation flaps close off, and in their absence protect the ventilation ducts with rags. In the summer, air ducts should be open. There is another ventilation option for a small room:
- Collect a box of planks with a section of 220 x 220 mm and set it vertically.
- Divide the internal section in half.
- Cover the top of the box.
- Seal and paint the outer part.
- Perform holes on the sides. One channel, which is located on the lee of the street, will be able to provide air to the room. Exhaust air exits through the other half of this ventilation shaft.
If the area is significant, the room will organize more complex ventilation. It is important to choose the right pipe diameter so that no drafts appear. For pipes, you can buy special round or rectangular valves with automatic valves.
Its main task is to create an optimal mode, regardless of the weather. In small farms, the installation of this hood does not always justify the costs associated with paying for electricity.
This method of ventilation resembles a supply and exhaust version, but in this case an improved technology is used, which consists in the use of fans. Sometimes the system is controlled manually, sometimes the control panel is included.
In the scheme of this ventilation there are two pipes and a fan, its location will depend on the type of circulation. To provide ventilation, it is installed in the inlet pipe. When arranging an effective hood, it is located in the exhaust pipe. The installation procedure is almost the same as that of the circulation system:
- 2 pipes are installed.
- Holes are drilled to get rid of condensate at the end of the chimney.
- Lay the electrical cable to the location of the fan.
- Install the switch. In this case, there are two options: a switch, which simultaneously turns on the lighting and a fan or a two-button switch, which makes it possible to control separately the hood and the light.
- Mounted fan.
In a simplified way, the fan is installed in the wall on the ceiling or mounted in a window. They measure the size of the fan, cut a rectangle of fiberboard according to the size of the glass unit. Mark and cut out the installation space, install the element in the frame and secure with screws. In the cut hole install directly fan. The method of attachment will depend on the design.
The fan connects to the mains. It is advisable to do the wiring outside the house, as there are inappropriate conditions inside. The main thing is to insulate the electrical wiring. This ventilation can not be left in operation for a long time. It is enough to turn it on for only a few hours a day and this is quite enough for the necessary ventilation.
This device is mounted on the roof. The principle of the deflector is as follows: it cuts the wind, which is directed in his direction, it reduces the pressure inside the deflector and increases the draft in the exhaust pipe.
Making your own wind turbine will be inexpensive, but the result will be impressive. Before you start manufacturing, you need to calculate the required dimensions. To calculate the height, it is necessary to multiply the section of the exhaust pipe by 1.8. Multiplying the cross section by 1.7, you can get the width of the cap, and while multiplying this figure by 1.4, you can find out the desired width of the diffuser.
Having determined all the sizes, they should be applied to the paper and cut the patterns. Then the sketches of the pillars and the cylinder, the sweep of the cap, the workpiece of the diffuser must be transferred to the steel sheet. With the help of scissors, a pattern is made of all the elements and connected with a rivet gun. Next you just need to attach the deflector.
Independently, you can make a rotary valve. Why do you need to weld a frame from the corners? On the sides of the frame, make holes and pass an axis into them. Sleeves are made of pipe pieces, and then welded.
From the metal sheet is made a locking plate, taking into account the size of the pipe. It is installed in a frame and attached to the axis by welding. To adjust the valve on the axis set the handle of the tree. To prevent the flap from opening on its own, it is necessary to provide a latch.
The disadvantage of this ventilation system is considered directly the fact of the presence of pipes in the hen house. After installing this hood, from its surface, as well as from the perch, you will need to regularly remove litter.
Any poultry farmer in his own way is trying to solve the problem with the ventilation system in the hen house. Some do not bother with its device at all until they are faced with the case of poultry and frequent diseases of chickens. Only after the occurrence of problems begin to choose between natural and forced ventilation, and then build it with his own hands without any problems.
Why do you need ventilation in the hen house
Like any other room for keeping animals and birds, the chicken coop must be ventilated. It should be understood that the regularly accumulated waste products of birds cause an unpleasant odor and increase the level of carbon dioxide.
Consequences of the lack of air circulation
Although poultry farming is a fairly common occupation, farmers often ignore the fact that the bird house needs regular airing. This is due to the fact that during the breeding of birds in the chicken coop, the level of carbon dioxide rises, which may entail not only the appearance of an unpleasant smell, but also a loss of egg production and the appearance of diseases in birds. In addition, thanks to the ventilation in the room you can control the temperature. The indicator of this parameter is very important, because the chicken's organism does not tolerate heat very well. If there is no ventilation in the hen house, then such effects as:
- loss of appetite in chickens, weakness and weight loss,
- negative dynamics of egg production,
- reduced immunity
- negative changes in temperature and humidity in the room.
Supply (exhaust) ventilation in the hen house
This ventilation is called forced-air and exhaust and is the most optimal for the maintenance of the chicken coop, because it is a convenient system of air circulation. For its installation it is necessary to place two pipes parallel to each other. Thus, on one of them air will flow into the room, and on the other - out of it.
To organize such a hood, you must perform the following sequence of actions:
- First you need to measure the distance from the floor to the ceiling. Then, using a hacksaw, saw off a part of the plastic pipe so that its upper end is located above the roof at a height of 20-30 cm, and the lower one - at a distance of 20 cm from the floor of the room. This design will perform the functions of the inlet pipe.
- After that, it is necessary to saw off another part of the pipe so that its upper and lower ends protrude 20-30 cm from different sides of the roof. This will be an exhaust pipe.
- For installation you need a drill with drills. With their help, you can make holes in the roof and install pipes.
- After that you can eliminate the gaps with mineral wool. It must be attached to the pipe with wire and wound around the pipe.

Features of winter ventilation in the hen house
The most practical option when maintaining bird housing in the winter is the supply and exhaust ventilation. Even if you installed it in the summer, it is always possible to improve the design, making it suitable in the winter. You can use the supply and exhaust system described above. For the construction of its necessary pipes. Their number depends on the area of the room. So, if it is less than 9 square meters. m, it can be limited to one pipe.
Tasks and the importance of ventilation in the hen house
The ventilation system is a mechanism for the circulation of air in the chicken coop, which provides fresh air and extracts of stagnant air masses.
Ventilation has the following functions:
- Ensuring the flow of oxygen
- Extract of carbon dioxide and ammonia vapors,
- Air humidity adjustment
- Temperature adjustment.
Carbon dioxide quickly accumulates in the confined space of a chicken coop, and when its concentration is more than 5%, chickens may start to choke.
In addition, chicken manure emits ammonia vapors into the air, which, if accumulated in a confined space, can be a strong poison for birds and can lead to respiratory diseases and a decrease in egg production.
The water evaporating from the drinkers and the chicken excretions create an increased humidity inside the chicken coop room, which can lead to breathing difficulties and sticking of feathers in birds. This is especially important when chickens are kept in cages, in crowded conditions, and regular intake of fresh air will prevent the active reproduction of bacteria and mold fungi that can cause a whole range of diseases in chickens.
The use of deep bedding and heaters in the absence of a ventilation system can lead to overheating of the air in the chicken coop.
Ventilation is necessary especially in winter, when it is not possible to walk the birds or air the room without chilling it.
Ventilation systems for the chicken coop can be of different types, depending on the principle of operation, design and method of arrangement. The most commonly used are the following:
- Supply and exhaust
Supply and exhaust ventilation type is based on the ability of warm air to expand and rise up. At the heart of the design - two plastic or metal pipes that go to the ceiling. The lower ends of the pipes should be located at different levels in height, as shown in Figure 1.
When heated, the air masses rush up and out through the exhaust pipe, and fresh air is drawn through the intake pipe into the resulting area with reduced pressure (in the lower part of the hen house). This design works automatically and around the clock, but there is a danger of running cold air in the winter.
When window ventilation on the opposite walls of the coop have small barred windows that open at the same time to "blow" the space of the coop. Window type allows you to quickly update the air in the room, but requires a favorable wind direction.
Mechanical design involves the installation of electric fans in window and ceiling openings. This method will provide a stable supply of fresh air, but will require the cost of electricity.
Combined ventilation systems will be effective, for example, when electric fans are built into the supply and exhaust design.
Supply and exhaust type
To install this type of ventilation system, the following materials and tools will be needed:
- Plastic water pipes with a diameter of 150-200 mm,
- Construction resin,
- Mineral wool
- Metal corners,
- Steel Reiki,
- Screws with a wide cap,
- Drill with screwdriver,
- Drill with a diameter of 10 mm for metal
- Tin or thin plywood for damper,
The drill is needed to make holes for pipes in the ceiling of the chicken coop. Therefore, you can use a drill of any diameter or jigsaw (for a wooden ceiling). Instead of mineral wool, you can use tow or any other insulation.
Plastic pipes can be replaced with metal ones only if there is a solid durable roof to which these pipes can be attached.
The procedure for the installation of ventilation of plastic pipes:
- Measure the height of the coop's ceiling,
- Saw a piece of plastic pipe with a hacksaw so that the upper end of the pipe could protrude 20-30 cm above the roof, and the lower end was at a distance of 20 cm from the floor of the chicken coop (this is a supply pipe),
- Saw off another piece of pipe so that its upper and lower ends protrude 20-30 cm on both sides of the roof (this is an exhaust pipe),
- Using the drill and drill in the roof, make two holes for the installation of pipes,
- Install the pipes into the prepared holes at the required height and attach them to the ceiling with metal corners,
- To seal up the gaps in the ceiling between the pipe and the holes with mineral wool, attaching it with a wire to the pipe in a circle,
- Pour construction resin on top of the roof pipe entry to prevent water from entering the chicken coop,
Install two horizontal rails on the bottom openings of both pipes using the corners,
- Attach to each rail two corners on each side, so that each pipe has 2 rails and 4 corners on them,
- Cut a rectangle out of a tin or plywood to the size of the space between the slats, then insert it between the slats and the corners in this way. So that he could slide horizontally around the corners, playing the role of a flap.
The damper serves as a regulator of the ventilation system, it can be covered in cold and windy weather so that the chickens do not catch cold.
If necessary, you can install additional fastening pipes to the wall with clamps, if the pipes are heavy enough. The lower end of the supply pipe is recommended to rest on a wooden stand in the form of a box.
The tops of the pipes protruding above the roof must be protected from rainwater by installing metal “umbrellas” on them, similar to chimneys.
This design can later be improved by connecting electric fans to the lower parts of pipes to accelerate the air flow.
Consider the features of the ventilation of the domestic chicken coop in the winter, how to install it without electricity? Far from the best option for airing in winter is natural ventilation.. Airing the room by opening the doors and windows gives serious heat loss, which leads to the death of livestock. Do not buy a heater?
In winter, passive ventilation has proven itself well, which removes dangerous vapors and provides access to fresh air. It has many advantages, in particular the following:
- no increase in electricity bills,
- round-the-clock autonomous work,
- performance of tasks
- silent work.
How to make a scheme without electricity?
- Before constructing ventilation, draw the scheme. It indicates the location of the two holes. They should be on opposite sides. Two corrugated pipes with a diameter of 0.2 m will pass through these holes.
- Near the nests and perches do not have a "supply" pipe. But the second hole is made, on the contrary, in the place where chickens walk, hatch eggs.
- According to the scheme, ventilation is constructed without worrying about heat loss: they will be absent.
Many poultry farmers buy and install a fan with temperature and humidity sensors in the exhaust pipe. for active air movement. To save electrical energy in the case of installing sensors, turn it on when dampness appears.
Each poultry farmer in his own way solves the problem with ventilation in the hen house. Одни не заморачиваются с ее обустройством вовсе, пока не столкнутся с падежом поголовья кур и его частыми болезнями.Only after the appearance of problems, they choose between forced-air and exhaust ventilation and natural ventilation, and then construct it themselves without much trouble.
