Chicken Litter Management and Welfare

The quality of litter in broiler houses directly affects bird welfare. Wet, dirty, or ammonia-laden litter causes foot pad lesions, burns, and respiratory disease — major welfare concerns at scale.

Key Facts

Broiler chickens in the US are raised on litter (wood shavings or similar bedding) indoors.
Wet litter from high stocking density and poor ventilation leads to foot pad dermatitis and hock burns.
Ammonia from litter exceeding 25 ppm causes eye and respiratory damage in birds.
Foot pad lesions are used as a welfare indicator in European auditing systems.
Better ventilation, lower stocking density, and litter amendments (like alum) improve litter quality.
Poor litter is linked to reduced weight gain and increased mortality, creating economic incentives for improvement.

Welfare Considerations

Litter quality is a foundational welfare issue for broiler chickens. Foot pad lesions, contact dermatitis, and ammonia-induced respiratory disease affect hundreds of millions of birds annually. These conditions are largely preventable through good management. Consumer pressure, certification standards, and retailer commitments to better chicken welfare have driven some improvements, but widespread adoption of best practices remains slow. Monitoring and auditing litter quality is essential to meaningful welfare progress.

What You Can Do

Support chicken welfare certification schemes that include litter quality standards.
Buy chicken from producers with verified higher welfare standards where available.
Encourage supermarkets to adopt Better Chicken Commitment pledges.
Advocate for mandatory foot pad lesion scoring and reporting by producers.
Learn about how stocking density and litter management intersect with bird health.
