Poultry Litter Management and Broiler Welfare: The Underfoot Problem

The quality of litter in broiler houses directly affects the welfare of billions of chickens. Wet, ammonia-saturated litter is one of the most pervasive and preventable causes of broiler suffering globally.

Key Facts

Hock burn — chemical burns from ammonia-saturated wet litter — affects the majority of conventionally farmed broilers in some surveys
Contact dermatitis on the footpads and breast of broilers is directly caused by litter quality failures and is a reliable welfare indicator
Good litter management including adequate ventilation, appropriate stocking density and litter turnover dramatically reduces contact lesion prevalence
Dry, friable litter also supports dustbathing, a fundamental broiler behaviour, and reduces respiratory disease from airborne pathogens
UK Red Tractor standards and RSPCA Assured both include litter quality monitoring as a welfare requirement, with consequences for poor performance

Welfare Considerations

Broiler litter welfare is an area where the welfare science, the production economics and the regulatory requirements are reasonably well aligned — wet litter is bad for birds, bad for growers and increasingly targeted by certification schemes. The challenge is consistent implementation at commercial scale. Consumer preference for welfare-certified chicken sends market signals that reward farmers who invest in litter management. Retailer procurement requirements and inspection feedback loops are the most direct quality improvement mechanisms.

What You Can Do

Choose broiler products from RSPCA Assured or equivalent certification schemes that include litter quality standards
Engage with retailers about litter quality requirements in their broiler supply chains
Advocate for mandatory hock burn and footpad dermatitis scoring to be published as welfare outcome data by producers
Support research into litter management innovations that reduce ammonia and wet litter conditions
Learn about hock burn and footpad dermatitis as welfare indicators when researching broiler production systems
