Broiler chickens — raised for meat — are the most numerous land animal on Earth, with billions living short lives under conditions that cause systematic suffering.
The modern broiler chicken is a product of genetic selection for rapid growth that has outpaced musculoskeletal and cardiovascular development. Birds as young as 3-4 weeks old can develop lameness that prevents normal movement, meaning they may spend days unable to reach food and water. Slower-growing breeds, lower density, and environmental enrichment meaningfully reduce suffering — and the Better Chicken Commitment has secured pledges from hundreds of companies.
