Stocking density - the number of birds per square meter of floor space - is one of the most extensively studied variables in broiler welfare. The evidence consistently shows that lower densities produce better welfare outcomes.
The science on broiler stocking density is clear and consistent: lower densities mean better welfare, and current legislative maxima are insufficient to protect welfare. The gap between the evidence and current standards reflects economic pressure from an industry where flock size directly determines revenue per shed. Achieving meaningful change requires a combination of regulatory leadership, clear consumer labeling that enables purchasing decisions aligned with welfare values, and procurement commitments from major food businesses. Individual consumer choices to purchase clearly labeled higher-welfare chicken support better industry standards.
