Poultry Litter Welfare: How Floor Conditions Affect Broiler Welfare

The condition of litter on poultry house floors has a direct and measurable impact on broiler chicken welfare, causing painful hock burns and breast blisters when poorly managed.

Key Facts

Hock burns (contact dermatitis on the hock joint) are a key welfare indicator in broilers
UK poultry welfare regulations require hock burn scoring and remedial action above threshold levels
Wet litter from poor ventilation, high stocking density, or digestive disturbances causes hock burns
Breast blisters develop when heavy, mobility-impaired broilers spend excessive time lying on wet litter
Hock burn prevalence varies dramatically between farms - from <5% to >80% depending on management
Litter quality is strongly influenced by stocking density, ventilation, and drinking system management
The EU broiler directive sets maximum stocking densities and requires welfare indicators including hock burn scoring

Welfare Considerations

Poultry litter welfare is an area where small management changes can have large welfare impacts for millions of birds. Hock burns cause chronic pain that affects bird behavior and welfare throughout their lives - birds with hock burns show reduced activity and modified gait. The direct link between litter condition and welfare outcomes means that litter management is not merely a production consideration but a welfare obligation. The variation between farms in hock burn prevalence demonstrates that poor litter management is not inevitable - it reflects management choices. Mandatory welfare indicator reporting creates accountability that drives improvement where producers know their data will be scrutinized.

What You Can Do

Choose chicken products with welfare certification schemes that include hock burn scoring requirements
Advocate for mandatory welfare indicator reporting including hock burn and breast blister data
Support lower stocking density requirements to improve litter condition and air quality
Engage with food companies about the welfare indicator data from their supply chains
Support ventilation improvement programs that maintain litter dryness
Reduce broiler chicken consumption or shift to slower-growing breed products
