The area and capacity of the chicken coop during the chicken raising process depends on the degree of mechanization and the management level of the farmer. The house built by the farmer can be determined according to the specific conditions of the site. The open chicken house should not have too much span. Otherwise, the ventilation and lighting of the house should be suffocating. The span of the house should be 6-9m. The span of the house with mechanical ventilation can reach 9-12m. The length of the house can be adapted to the local conditions. For large-scale chicken houses on the scale, it can be designed to be 7-8m wide, 33-53m long, 2800-5000 caged laying hens; large and medium-sized chicken houses can be designed to be 10-12m wide and 40-65m long, caged laying hens 5000 -10000 only.
The height of the house should be determined according to the farming method, method of cleaning the manure, span and climatic conditions. Generally, the distance between the top of the cage and the roof is 1.5m.

The wall of the house has good thermal insulation performance, simple structure, easy to clean, clean and disinfect, and strong earthquake resistance. The climate is cold and the area is properly thickened; in the climate-friendly area, the walls can be slightly thinner. The outside of the wall is covered with cement, and the inner wall is covered with cement or white lime.

The floor of the chicken house should be waterproof, solid, flat and smooth, not slippery, corrosion-resistant, have certain insulation properties, moisture-proof, no water accumulation, easy to clean and disinfect. Generally, it should be 20-30cm above the ground in the field to create a high dry environment. In order to facilitate drainage and avoid the accumulation of sewage, the slope on the inner ground should be 2%–3% in the direction of the drainage ditch.

Doors, windows and venting doors are generally located on the south side of the south-facing house. The size of the door should be considered for all equipment and work vehicles to enter and exit smoothly. Generally, the single door height is 2m and the width is 1m; the two doors are 2m high and 1.6m wide. The window of the chicken house should consider the lighting and ventilation of the chicken house. The open house can be set on the front and rear walls, and the front window should be large. It can be lower from the ground to facilitate daylighting. The rear window should be small, about 2/3 of the front window, which can be slightly higher from the ground to facilitate summer ventilation. In the chilled area of ​​the house, the number of windows should be as small as possible, as small as possible, under the premise of satisfactory lighting and summer ventilation. Although the closed house does not require windows to provide light and ventilation, it should also be equipped with some emergency windows to prevent the sudden need for accidents such as power outages. At present, the simple and energy-saving open-type chicken house, which is popular in China, has a large-scale multi-functional FRP ventilation window on the north and south walls of the chicken house. It is a translucent wall that can be opened and closed. This window has two windows and walls. Layer effect. Ventilation settings vary depending on the method of ventilation. For naturally ventilated houses, a row of vents should be placed evenly on the top of the longitudinal wall of the house. The chicken house with mechanical ventilation method is provided with the air inlet and the exhaust port symmetrically. So when we keep chickens, it is also good for chicken cages.
