The blue light is likely to induce chicken gizzards, reducing the resistance to disease in chickens of all ages and reducing the egg production rate of adult hens. Therefore, the chicken should not use blue lighting for his whole life.

Yellow light can reduce the egg production rate of adult hens and breed hens to reduce the fertilization rate. Therefore, it is forbidden to use yellow lighting for laying hens
and breeding hens. The yellow light will also induce chicken gizzards, so it is inappropriate to use yellow light lighting for chickens of all ages.
