Farm Animal Welfare: Broiler Stocking Density Effects

Stocking density in broiler production has direct, dose-dependent effects on welfare outcomes including footpad health, gait quality, fear and mortality.

Key Facts

Maximum EU stocking density for broilers is 33 kg/m2, rising to 42 kg/m2 with additional conditions
At high densities, footpad dermatitis, hock burns and aggression increase proportionally
Lower stocking densities improve gait quality, fearfulness and access to enrichment
The Better Chicken Commitment requires maximum 30 kg/m2 stocking density
Litter quality at high density deteriorates rapidly, worsening footpad welfare

Welfare Considerations

Stocking density is one of the most powerful determinants of broiler welfare, with clear dose-response relationships between density and welfare outcomes. Reducing density from 42 to 30 kg/m2 represents a 28% improvement in individual bird space and produces measurable welfare improvements across multiple indicators simultaneously. Consumer and retailer commitments to lower stocking density standards represent some of the most impactful welfare interventions in commercial poultry.

What You Can Do

Choose chicken products from Better Chicken Commitment-compliant brands
Ask supermarkets about their maximum stocking density standards for chicken suppliers
Advocate for 30 kg/m2 maximum to become the legal standard in national poultry welfare codes
