Poultry Keel Bone Fractures: Industry Reform

Keel bone fractures affect the majority of laying hens in many production systems, representing a major and largely overlooked welfare issue.

Key Facts

Post-mortem studies find keel bone fractures in 50-80% of laying hens at end of lay
Fractures cause significant pain and reduced mobility affecting natural behaviours
Aviary systems paradoxically increase fracture risk due to collision during flight
Genetics, nutrition, and early-life bone development all influence fracture risk

Welfare Considerations

Keel bone fractures represent one of the most prevalent sources of pain in modern laying hen production. Industry reform requires a multi-factorial approach addressing genetics, housing design, and management practices simultaneously.

What You Can Do

Support laying hen breeds with improved bone strength where choice is available
Advocate for keel bone fracture prevalence to be included in welfare assurance audits
Engage with research organisations developing solutions to keel bone fractures
