Stocking Density and Welfare in Poultry Production

Stocking density is one of the most powerful determinants of welfare outcomes in commercial poultry production, affecting movement, air quality, litter condition, and stress.

Key Facts

EU law sets maximum of 33 kg/m2 for standard broilers, 42 kg/m2 with audited enhanced conditions
Higher stocking densities correlate with increased leg disorders and mortality
Litter quality deteriorates rapidly at high density due to high ammonia and moisture
Freedom to move is a key welfare indicator compromised by high density
Free-range and organic standards set significantly lower stocking limits

Welfare Considerations

High stocking density prevents natural behaviour including foraging, dust bathing, and exploration. Poor litter quality causes hock burn and foot pad dermatitis in overcrowded flocks. Reduction in stocking density is one of the most effective welfare interventions available to the poultry industry.

What You Can Do

Choose free-range or organic chicken to support lower stocking densities
Support welfare labelling schemes that include stocking density information
Advocate for stricter stocking density limits in poultry regulations
