Poultry Litter Management and Broiler Welfare

The quality of litter in broiler chicken housing is one of the most important determinants of welfare, affecting foot health, respiratory function, and overall bird comfort. Effective litter management is both a welfare imperative and an economic priority.

Key Facts

Broilers are raised on litter — wood shavings, straw, or other absorbent material — on the floor of windowless sheds throughout their short lives
Wet, compacted litter is the primary cause of hock burn and footpad dermatitis — painful skin lesions affecting the majority of conventionally farmed broilers
Footpad dermatitis prevalence rates at slaughter are used as a welfare monitoring indicator in several European countries, including the UK's slaughterhouse monitoring scheme
Litter quality depends on stocking density, ventilation effectiveness, watering system management, and flock health status
High-quality dry litter supports natural behaviours including dustbathing, which is strongly motivated in broilers despite their short lives
Ammonia released from wet litter causes respiratory irritation, eye disease, and chronic airway inflammation in birds exposed at high concentrations

Welfare Considerations

Litter quality represents one of the most direct welfare levers available to broiler producers because it determines the surface on which birds spend every minute of their lives. Wet, ammonia-saturated litter causes chemical burns to skin in contact with it — footpad dermatitis is painful and affects locomotion, feeding, and overall welfare. A bird with severe footpad dermatitis that cannot walk to feed and water points suffers both from the lesion itself and from secondary nutritional deprivation. The management factors that maintain litter quality are well-understood: appropriate stocking density to prevent excess moisture; effective ventilation to maintain airflow and dry the litter surface; nipple drinker adjustment to prevent leakage; and monitoring of bird health to catch enteric disease that causes wet litter. Higher-welfare systems with outdoor access allow litter drying naturally and further reduce the time birds spend on indoor litter surfaces.

What You Can Do

Choose chicken from farms with certified low footpad dermatitis prevalence — this is a visible welfare indicator
Support regulatory requirements for slaughterhouse footpad scoring and its use to trigger farm management interventions
Advocate for improved ventilation standards in broiler housing to maintain litter quality year-round
Support research into litter additives and management practices that reduce footpad dermatitis prevalence
Reduce chicken consumption or shift to certified higher-welfare chicken to create market pressure for litter quality improvement
