Broiler Chicken Welfare Science

Scientific research on broiler welfare has identified key risk factors and interventions that improve outcomes for billions of birds.

Key Facts

Over 60 billion broilers are produced globally each year
Fast-growing breeds develop leg problems and cardiovascular disease
Mortality from welfare-related causes is a key welfare indicator
Slower-growing breeds show significantly improved welfare outcomes
Stocking density affects air quality, litter condition, and bird welfare

Welfare Considerations

Broiler chicken welfare science has advanced significantly in recent decades, identifying the welfare trade-offs between fast growth and health. Birds bred for extreme growth rates suffer from skeletal abnormalities, heart failure, and reduced ability to express natural behaviours. Evidence clearly supports that slower-growing breeds and lower stocking densities improve welfare outcomes.

What You Can Do

Choose chicken products from slower-growing breed programs
Support welfare standards that include breed and stocking density requirements
Advocate for retailer commitments to higher welfare chicken
Support research into broiler welfare indicators
Encourage adoption of validated welfare outcome measures on farms
