Poultry lighting is requested to be flicker-free primarily because chickens are highly sensitive to light fluctuations, which can cause stress and negatively impact their behavior and performance. Flicker-free lighting reduces this stress, leading to improved productivity, reduced pecking, and better overall welfare. 

Here's a more detailed explanation:

Sensitivity to Flicker:

Chickens can see flicker at a higher frequency than humans, and even slight fluctuations can be perceived as irritating or alarming. 

Stress and Behavior:

Flickering lights can cause stress in poultry, leading to behaviors like pecking, increased mortality, and reduced egg production. 

Improved Welfare:

Flicker-free lighting promotes a more calming environment, leading to improved animal welfare and potentially better performance. 

Economic Impact:

By reducing stress and improving behavior, flicker-free lighting can contribute to increased egg production, better growth rates, and overall economic benefits for poultry farms.
