Like other animals, chickens react instinctively to certain light hues. It has been discovered via scientific study that hens react differently to various light hues. In particular, red light may irritate hens, but blue and green light cause them to react favorably.
Research has shown that hens reared in blue and green light have a more composed temperament, enhanced well-being, and superior growth and development in general. This is probably because hens are used to responding to natural sunshine, which is what these hues resemble.
Because it helps hens make melatonin, which promotes relaxation and sleep, and regulates their circadian cycles, blue light has been discovered to have a relaxing impact on them. Chickens may benefit from green light as well, since it can boost their immune systems and lessen aggressiveness and anxiety.
Chickens, on the other hand, react to red lights less well. Due to the disruption of their regular day/night cycle and potential effects on their eating and breeding behaviors, red lights have been shown to elicit stress and agitation in hens. Red lights should thus not be used in chicken coops or any other location where hens are housed.
Hence, blue or green light may assist your hens rest and maintain their circadian cycles, which will help you create a peaceful and healthy atmosphere for them. This will not only increase their well-being but also promote greater development and growth. You may raise happy, healthy hens by taking note of how light affects them and making changes to their general quality of life.
