Farmed Broiler Chicken: Lighting Management and Welfare

Lighting management in broiler chicken production profoundly affects welfare, with natural light access, appropriate daylength, and darkness periods being critical for normal behaviour and health.

Key Facts

Conventional broiler production often uses near-continuous artificial lighting to maximise feed intake
EU regulations require at least 6 hours of darkness per 24 hours in broiler houses
Natural light access is associated with increased activity, better bone strength, and lower leg disorder rates
Dimly lit conventional houses create monotonous visual environments that limit exploration behaviour
Higher welfare standards such as RSPCA Assured mandate minimum lux levels and natural light access
Photoperiod manipulation to maximise early weight gain compromises circadian rhythm welfare

Welfare Considerations

Lighting conditions determine the entire sensory and behavioural environment of broiler chickens. Birds in conventional dim, near-continuous lighting live in a state of reduced activity and sensory monotony that prevents normal behaviour expression. Darkness periods are not merely regulatory requirements - they are essential for circadian rhythm entrainment, immune function, and psychological wellbeing. Natural light access enables environmental exploration and provides visual stimulation that supports normal cognitive functioning. Lighting reform is a low-cost, high-impact welfare improvement that the industry resists primarily for marginal production efficiency reasons.

What You Can Do

Choose chicken certified by higher welfare schemes mandating natural light and adequate darkness
Support regulatory reform requiring minimum natural light provision in all broiler houses
Ask poultry producers about their lighting management standards
Advocate for science-based lighting standards that prioritise bird welfare over feed conversion
Reduce conventional broiler consumption while supporting welfare-labelled alternatives
