Hen Keel Bone Fractures - Prevention and Management

Understanding keel bone fractures in laying hens, their welfare impact, and prevention approaches in modern housing systems.

Key Facts

Keel bone fractures affect 50-80% of laying hens in commercial flocks by end of lay
Fractures cause chronic pain measurable through altered behaviour and reduced welfare-relevant indicators
Aviary housing increases fracture rates compared to enriched colony cages due to falling and collisions
Selective breeding for keel bone strength is producing measurable improvements in bone density
Pain assessment using the Hen Grimace Scale enables identification of individuals requiring management intervention
