The breed of chicken profoundly affects welfare outcomes. Fast-growing broiler breeds face severe health problems while slower-growing alternatives offer substantially better welfare.
Breed selection is arguably the single most consequential welfare decision in poultry production. Fast-growing breeds are physiologically compromised by their own growth rate, experiencing chronic pain, reduced mobility, and cardiovascular stress throughout their short lives. Welfare science is unambiguous: slower-growing breeds have significantly better welfare outcomes across all key indicators. Major food companies committing to the Better Chicken Commitment and similar standards are responding to this evidence. Consumer pressure and corporate commitments are accelerating breed transitions in some markets.
