Keel bone fractures: a widespread and underaddressed issue

Laying hens

of UK laying hens have broken or deformed keel bones — a figure that research suggests may significantly underestimate true prevalence.

Welfare & productivity

Affected hens show reduced mobility, spend less time at feeders, and display elevated stress indicators. There is also emerging evidence of productivity effects, including reduced laying persistence.

Neglected

Despite its prevalence, the issue remains under-researched relative to other welfare concerns, and is not yet addressed by most welfare standards in the industry.

Keel bone fractures (KBFs) are breaks and deformities of the sternum — the long bone running along a hen's chest — common in commercial laying flocks across all housing systems.

Research, collaboration, and advocacy

Research

We work with leading academic institutions to consolidate and extend the evidence on keel bone fracture prevalence, causes, and interventions.

Collaboration

We bring together researchers, producers, and industry bodies to connect the right people and translate findings into practical progress on farms.

Advocacy

We engage with the bodies that set standards for the egg industry, making the case for evidence-based welfare improvements and supporting the process of change.
