How to build a henhouse for raising laying hens

Ventilation design: when building a chicken coop, you need to design windows and protect it with barbed wire, and if it is a windowless chicken coop, you need to install a ventilator. Disinfection pool: disinfection pool can be set at the entrance of the chicken house, the floor inside the house should be higher than the outside, and drains can be designed around the chicken house. Cold and heat prevention: the thickness of the north wall brick should be strengthened and the roof should be installed. Chicken house lighting: the chicken house is built in the south-facing north position or set up artificial lighting equipment. Chicken house roof: single-slope roof and double-slope roof.

I. ventilation design

1. In the construction of the chicken house, ventilation should be considered in advance, because the metabolism of the chicken is relatively fast, and in this process, the demand for gas is relatively large, so there are more harmful gases.

2. Therefore, the ventilation condition of the chicken house must be good. The chicken house can design windows, which are mainly conducive to ventilation. If the chicken house has windows, we must pay attention to protection. Barbed wire can be used for protection to prevent birds and animals from entering the chicken house, so as to reduce the spread of the disease.

3. If it is a windowless chicken coop, it is necessary to install a fan, which is beneficial for the chickens to absorb the fresh air and discharge the harmful gas.

2. Disinfection pool

1. Daily chicken sheds need to be disinfected and sterilized regularly, which is conducive to the prevention and control of various epidemic diseases, so as to ensure the healthy growth of chickens.

2. Under normal circumstances, water is needed for sterilization and disinfection, so it is necessary to facilitate the discharge of sewage from the mixture of water and chicken house debris. Therefore, the internal demand of the chicken house is higher than that outside the chicken house, which is about 0.2-0.3m higher. Then a drainage ditch can be designed around the chicken house, and a disinfection pool can also be set up at the entrance of the chicken house.

Third, heat preservation and heat prevention should be good

1. When building a chicken house, we must consider the protection against cold and heat, and the suitable growth temperature for chickens is about 10-23 ℃.

2. If the temperature is lower than 5 ℃ in winter, the feed intake of chickens will increase, thus reducing the feed utilization rate. The higher temperature in summer will affect the normal growth of chickens, so it is necessary to install a ceiling on the roof of the chicken house to strengthen the thickness of the north wall tiles.

Fourth, chicken coop daylighting

1. Natural light or artificial lighting equipment must be used in the construction of chicken sheds. Reasonable lighting is beneficial to heat preservation, sterilization and disinfection, so as to promote the growth of chickens.

2. The henhouse facing south and north is more favorable for light, and more light can be obtained when the light angle is oblique in winter and straighter in summer, which can reduce the direct sunlight.

Fifth, the roof of the chicken house

The roof of the chicken house must be designed, and a ceiling can be set up to fill rice husks on it, which helps to insulate the heat. The roof can generally use single-slope and double-slope roofs, and its edges need to focus on streamlined design, which is conducive to Rain Water's downstream and shade.
