The closed chicken house is also called a closed windowless chicken house. The roof and the four walls of the house are well-insulated; there are no windows on either side, and the home environment is mainly regulated by manual or instrument control, resulting in an “artificial climate” in the house. That is, artificial ventilation and light are used to control the temperature, humidity and air content in the house by changing the amount of ventilation.

Advantages: stable environment, not easily affected by natural environmental conditions; production is stable and safe; through the manual control of operating techniques, it is conducive to controlling the growth and development of chickens, sexual maturity and stimulate the laying cycle, to facilitate the quality and quantity of chickens monitor. Such as restrictions on feeding, forced moulting and other measures.

Disadvantages: Building standards and ancillary equipment requirements are relatively high, investment is relatively large, and the flocks are completely out of any conditions of natural breeding. The environment and conditions for the growth and production of the flock are completely created by artificial means, and therefore the full price of the feed is required to be high. This method is suitable for northern regions.
