Chickens and humans see the world differently, which can be attributed to the difference in natural habitats. Chickens are originally from the jungles of Southeast Asia. Due to this different environment, poultry are more sensitive to the red and blue spectrums which are not filtered by the canopy of the jungle. Poultry’s green light perception is comparable to humans as they usually get similar exposure. Chickens are also able to see UV light which allows them to see enhanced coloring. For example, the pictures of this butterfly would give a better idea of how the world would be interpreted.
Now knowing that chickens’ eyes are different than ours, wouldn’t it be in their best interest for your artificial lighting systems to be tailored to them? Adding our species-specific color spectrum with a sunrise/sunset simulation will greatly improve your poultry’s welfare and productivity.
