Broiler Chicken Lighting Welfare

Lighting conditions in broiler houses profoundly affect chicken behavior, health, and welfare throughout the production cycle.

Key Facts

Dim continuous lighting was historically used to reduce activity and boost weight gain
Broilers under very low light show increased fearfulness and leg problems
Intermittent lighting programs improve welfare and reduce leg disorders
EU regulations now require minimum 6 hours of darkness per 24-hour cycle

Welfare Considerations

Light programs affect circadian rhythms, activity levels and bone development. Chickens need darkness to rest properly and exhibit natural behaviors. Continuous dim light suppresses activity, leading to cardiovascular and skeletal problems that cause significant suffering.

What You Can Do

Choose chicken certified under enhanced welfare standards
Ask producers about lighting protocols
Support research into optimal lighting for broiler welfare
Advocate for minimum darkness requirements in regulations
