Broiler Chicken Welfare: Addressing Fast-Growth Problems

Fast-growing broiler chicken breeds, selected for rapid muscle growth, suffer widespread welfare problems including leg disorders, cardiovascular disease, and inability to perform natural behaviors. Reform is possible and gaining traction.

Key Facts

Over 70 billion broiler chickens are produced globally each year — more than any other farmed terrestrial animal
Modern commercial breeds reach slaughter weight (2.5 kg) in 35-42 days, compared to 84 days in 1950
Leg disorders affect 30-50% of commercial broilers, causing chronic lameness and pain
Ascites (fluid around the heart/lungs) and sudden death syndrome kill millions annually due to cardiovascular strain
Hockburn and footpad dermatitis affect majority of birds in high-density indoor systems
Fast-growing breeds spend 76-86% of their time lying down, compared to 65% in slower-growing breeds
The Better Chicken Commitment (BCC) calls for adopting slower-growing breeds and higher welfare standards
Over 200 major food companies globally have made BCC or equivalent commitments

Welfare Considerations

Broiler chicken welfare represents one of the largest-scale animal welfare challenges in existence. The genetic selection for rapid growth creates inherent physiological suffering — bones and cardiovascular systems cannot keep pace with muscle development. Lameness causes chronic pain that alters behavior, reduces feed and water access, and is often untreated. High stocking densities (typically 30-40 kg/m²) prevent expression of natural behaviors including foraging, dust bathing, and social interaction. Litter quality deteriorates rapidly at high densities, causing foot and hock lesions. The transition to slower-growing breeds substantially reduces leg disorder prevalence and improves mobility, with welfare benefits demonstrated across multiple independent studies.

What You Can Do

Choose chicken products from farms committed to slower-growing breeds and higher welfare standards
Support food companies that have adopted the Better Chicken Commitment
Reduce overall chicken consumption and shift spending toward higher-welfare products
Ask retailers and restaurants about their chicken welfare policies
Support corporate campaigns and petitions calling for better broiler welfare standards
Stay informed about welfare certifications such as RSPCA Assured, Certified Humane, or equivalent in your country
