What is the purpose of red light in chicken barns?

Red light in chicken barns primarily serves to control cannibalism among the flock. This is particularly important in situations where birds may exhibit pecking behavior towards each other, which can lead to injury or mortality. The use of red light helps to reduce the visibility of blood or injuries, which can further provoke aggressive behaviors among chickens. By softening the visual stimuli that can trigger such responses, red lighting plays a vital role in maintaining a calm environment that minimizes stress and aggression, ultimately leading to healthier birds.

While red light may contribute to other factors in poultry management, its primary recognized benefit is in reducing instances of cannibalism. This is crucial for ensuring the welfare of the birds and maintaining productivity in egg-laying and broiler operations.
