Broiler Chicken Fast Growth Leg Health Problems

Modern fast-growing broiler breeds develop serious leg disorders due to extreme growth rates. Skeletal disease is one of the most significant welfare concerns in poultry production.

Key Facts

Fast-growing broilers reach slaughter weight in 35-42 days compared to 81+ days for slower breeds
Up to 25-30% of fast-growing broilers show observable gait abnormalities before slaughter
Tibial dyschondroplasia, valgus-varus deformity and contact dermatitis are common conditions
Lameness prevents access to feed and water causing hunger and dehydration in severe cases
Switching to slower-growing breeds like Hubbard JA87 or Ranger Classic dramatically reduces leg problems

Welfare Considerations

Broiler lameness causes measurable pain and distress confirmed by studies showing lame birds will choose pain-relieving feed supplements. Extreme growth rates select inherently for skeletal inadequacy. The most impactful welfare improvement available in chicken production is transitioning to slower-growing breeds, which major food companies are now committing to under Better Chicken Commitment standards.

What You Can Do

Choose chicken certified under Better Chicken Commitment or equivalent slower-growth standards
Ask fast food and restaurant chains whether they have adopted Better Chicken Commitment pledges
Reduce chicken consumption or shift to certified higher-welfare sources
Support organizations campaigning for mandatory slower-growing breed requirements
Write to supermarkets asking about their progress toward Better Chicken Commitment targets
