Construction type of egg house
Currently, there are two types of buildings in egg houses: closed and open. Closed-type chicken houses are also called windowless chicken houses. This type of chicken house is equipped with an emergency window. It is usually closed when the power is turned off. It is usually closed, artificial lighting is used, mechanical ventilation, mechanical feeding, and ideas are applied once. Sex excrement, chickens in the closed environment of artificial control, less interference by the outside world, is conducive to the growth and development of chickens and egg production. However, one-time investment is large, construction costs are high, and lighting, ventilation, cooling, etc. all rely on electricity. Depends on the power source very much, the power consumption is very high, cannot use without the power source guarantee. Due to the high density of closed chicken houses, there must be good ventilation and cooling facilities in the summer, otherwise hot dead chickens and egg production rates will decline. The open type chicken house is also called a window chicken house. During the day, natural light is used. The ventilation and ventilation of the same powder and the control of temperature are adjusted by opening and closing the windows. This type of chicken house has a thoroughbred form: one is a chicken house with a window and brick structure; the other is an open-type roller blind chicken house developed by Beijing Agricultural University, and the ventilation and light control are controlled by the lifting of the roller blinds to control the temperature. . Roller blinds have good ventilation, but they have poor thermal insulation in winter and are only suitable for use in areas south of North China. Open chicken houses are low in cost, use natural light, natural wind, and natural heat, so they save energy, but they cannot control the light and are easily disturbed by external conditions. As long as the husbandry is managed properly, high yields can be obtained regardless of the closed chicken house or the open chicken house. At present, most chicken farms in China use open chicken houses, while more neurotic chickens may be better kept in closed chicken houses. This kind of chicken house is quiet and the chicken population is not stimulated by the outside and can maintain high and stable yields. .
