Stocking density in broiler chicken production is a primary determinant of welfare outcomes, with research consistently showing that lower density improves virtually every welfare indicator.
Stocking density represents one of the most straightforward welfare interventions in broiler chicken production: less crowding means better welfare across nearly every measurable dimension. Lower density means better litter quality (less ammonia, less footpad dermatitis), more space for movement (less lameness), better air quality (less respiratory disease), and more normal social behavior. The economic case for reducing density is stronger than commonly assumed — lower mortality and medication costs partially compensate for fewer birds per square foot. The Better Chicken Commitment's 30 kg/m² maximum is a pragmatic policy goal that major food companies have committed to. Corporate commitment adherence monitoring and consumer pressure sustain progress.
