Windowless poultry house - Windowless poultry house
A chicken coop with a closed, insulated structure without windows, which blocks out natural light and allows for effective artificial lighting, is primarily intended to regulate the day length that affects chicken growth and egg laying. It is also called a windowless chicken coop. The temperature and humidity inside the coop are regulated by mechanical ventilation. By increasing the amount of ventilation, it is possible to raise more chickens in the same area, and it is also valued for reducing pollution to the surrounding area caused by the sounds and odors of chickens.

ニワトリの発育や産卵に影響をおよぼす日長時間を調節することを主目的とし,自然光を遮断して人工照明を効果的に行えるようにした,窓のない閉鎖型断熱構造の鶏舎。無窓鶏舎ともいう。舎内の温度や湿度は機械換気によって調節する。換気量を多くすることによって,同一面積で多くのニワトリを飼うことができる点や,ニワトリの鳴声および臭気による周囲への公害を少なくできる点も評価されている。養鶏【野附 巌】
