These experiment manifest what impact the birds are wavelength instead intenstive. Of cource its influence could not be excluded.Just like other birds, layer hens’s eyes are really senstive to the light, which are crucial in the growth environment. To manipulate various factors of LED lighting can control the chicken behaviors and production.
