Hen Welfare and Keel Bone Prevention Strategies

Keel bone fractures affect the majority of hens in many systems. Evidence-based prevention strategies including breed selection, perch design, and early exposure can reduce this welfare crisis.

Key Facts

Keel bone fractures affect 50-80% of hens in cage-free and enriched colony systems
Fractures cause chronic pain that is often unrecognised
Lower breast angle genetics and bone mineral density are key risk factors
Early-life perch use improves bone strength and reduces fracture risk
Perch geometry including diameter and gradient significantly affects fracture rates

Welfare Considerations

Keel bone fracture is the most significant welfare problem in laying hen production, yet many farms lack systematic monitoring or prevention programmes. Targeted interventions can substantially reduce this prevalent welfare harm.
