2. Type of henhouse: There are two kinds of henhouses: open henhouses (common henhouses) and closed henhouses. The most common form of open chicken coop is that there are walls on all sides, big windows on the south wall and small windows on the north wall. All or most of these henhouses rely on natural ventilation and natural lighting, and the temperature and humidity in the henhouses basically change with the seasons. Such henhouses often need to be equipped with ventilation and lighting equipment to supplement the lack of ventilation and lighting under natural conditions. Closed henhouse is also called windowless henhouse. The four walls of the roof of this henhouse have good heat insulation, and there are no windows on all sides. The indoor environment is controlled and adjusted manually or by instruments. The henhouse adopts artificial ventilation and illumination, and the temperature, humidity and air composition in the henhouse are controlled by changing the ventilation volume.

3. The structure of each part of the henhouse requires that the foundation and foundation should be deep and solid. The ground is higher than the house, moisture-proof, flat and easy to clean and disinfect. The wall has good thermal insulation performance and can resist the external wind and rain. Brick or stone masonry, cement plastering on the outside of the wall, and cement or lime plastering on the inside of the wall are used for moisture prevention and scouring. The roof is generally double-sloping, and only the single-sloping roof can be used for small-span henhouses.

4. Doors and windows are generally located in the south of the henhouse. Generally, a single door is 2m high and 1 m wide; The two doors are 2m high and 1.6m wide. The windows of the open henhouse should be located on the front and rear walls, and the front window is wide and low from the ground, which is convenient for lighting. The ratio of window to floor area is1:10-18; The rear window is small, with an area of about 2/3 of the front window, and it is high from the ground, which is convenient for ventilation in summer. The closed henhouse has no windows, only emergency windows and ventilation holes.

5. The span, length and height of henhouse depend on the form of roof, the type of henhouse and the feeding method. Generally, the open chicken coop is 6-10m, and the closed chicken coop is12-15m. The length of henhouse generally depends on the span of henhouse and the degree of mechanization of management. A chicken coop with a span of 6- 10 meter is generally 30-60 meters long; A hen house with a large span, such as12m, is generally 70-80m long.

6. A chicken coop with a higher degree of mechanization can be longer, but generally it should not exceed 100 meter. The height of the henhouse should be determined according to the feeding method, feces cleaning method, span and climatic conditions. In areas with small span, dry farming and low temperature, the henhouse need not be too high, and the height of the eaves of the henhouse is generally 2-2.5 meters; For long-span and multi-layer cages, the height of the henhouse can reach about 3 meters, or the top henhouse is L- 1.5 meters away from the roof. If it is a high-bed closed chicken coop, the height is generally 4.5-5 meters because there is a cesspit at the lower part.

7. The operation room and aisle operation room are places where breeders operate and store tools. If the length of the henhouse is less than 40 meters, the operation room can be located at one end of the henhouse; If the length of the henhouse is more than 40 meters, it should be located in the center of the henhouse. The location of the walkway depends on the span of the henhouse. When the span of a flat chicken coop is small, the walkway is generally located at one side of the chicken coop, and the width is1-1.2m; When the span is more than 9 meters, a walkway with the width of 1.5- 1.8 meters shall be set in the middle for trolley feeding. No matter how big the span of the henhouse is, the walkway between the henhouses should depend on the layout of the henhouses. Generally speaking, the aisle width between cooperatives is 0.8-1m.
