Optimal Lighting Design for Chicken Coops: Key Considerations Based on Research
Light Intensity Preferences and Zoning
Broiler chickens exhibit a clear preference for higher light intensities (20 lux) in feeding areas compared to dimmer environments (5 lux). A study demonstrated that 20 lux lighting significantly increased feed consumption and attracted more birds to feeders, suggesting that feeding zones should maintain at least 20 lux for optimal activity. Conversely, reducing light intensity to 1–2 lux in resting areas (e.g., transit zones) did not deter chickens, supporting a zoned lighting approach to balance energy use and welfare.
Dynamic Lighting Programs
Intermittent lighting programs, which alternate periods of light and darkness, have proven effective in enhancing productivity while reducing energy consumption. For instance, combining intermittent lighting with red-colored feeders improved weight gain and feed conversion in broilers, indicating that light schedules and spectral cues can synergistically influence behavior and performance. This approach allows energy savings without compromising growth metrics.
Light Source Selection
LED lighting outperforms traditional compact fluorescent lamps (CFL) in poultry environments. Chickens under white LED lighting showed higher feed intake at critical growth stages (21–35 days) and better overall production metrics, including lower mortality rates and improved feed conversion ratios. While birds did not display a preference between white and yellow LED light colors, the energy efficiency and durability of LEDs make them ideal for long-term use.
Spectral and Behavioral Modulation
Monochromatic lighting, particularly red wavelengths, has been linked to positive behavioral and physiological outcomes. Red light may reduce aggression and stress, aligning with findings that red feeders enhance performance under intermittent lighting. Additionally, adaptive lighting systems mimicking natural daylight cycles can support circadian rhythms, potentially mitigating stress and improving welfare.
Practical Design Recommendations
Zoning: Implement 20 lux in feeding areas and ≤5 lux in resting zones.
Energy Efficiency: Use programmable LED systems for adjustable intensity and spectrum.
Stress Reduction: Incorporate red lighting in feeders or activity zones to optimize behavior.
Maintenance: Prioritize durable, easy-to-clean fixtures (e.g., marine-grade materials) to withstand coop conditions.
