Broiler Stocking Density and Welfare

Stocking density in broiler chicken houses is one of the most important determinants of welfare, with higher densities associated with worse health and behavioural outcomes.

Key Facts

EU regulations permit maximum stocking densities of 33-42 kg per square metre
RSPCA Assured standard requires maximum 30 kg per square metre
High stocking density impairs access to water and feed, and reduces activity levels
Litter quality deteriorates faster at higher densities increasing foot pad dermatitis
Lower density flocks show more activity, better gait, and reduced mortality

Welfare Considerations

High stocking density creates a cascade of welfare problems including competition for resources, impaired air quality, poor litter condition, and reduced ability to move freely. Evidence consistently shows improved welfare outcomes at lower densities. The economic pressure to maximise density must be balanced against welfare standards. Consumer choice of higher welfare chicken drives demand for lower density production.

What You Can Do

Choose RSPCA Assured or higher welfare chicken specifying density limits
Support retailers committing to lower density broiler standards
Advocate for EU maximum density standards to be reduced to better reflect welfare evidence
Reduce chicken consumption or choose higher welfare options
Support research into optimal stocking density for broiler welfare
