Providing environmental enrichment including perches, pecking objects, and natural light to broiler chickens improves welfare and behavior without significantly compromising production outcomes.
Broiler chickens in barren houses with no opportunity to perch, peck at objects, or experience varied light conditions spend most of their lives sedentary and behaviorally unstimulated. This contributes to poor leg development, reduced cardiovascular fitness, and high rates of contact dermatitis from prolonged lying on wet litter. Enrichment provision is one of the most accessible welfare improvements in broiler production and is increasingly required by retailer commitments and welfare certification schemes.
