Hen Welfare: Perch Access and Bone Strength

Laying hens that lack access to perches suffer from severe osteoporosis and bone fractures — one of the most widespread welfare problems in commercial egg production.

Key Facts

Up to 50% of hens in cage systems suffer bone fractures before slaughter
Perch use strengthens bones through weight-bearing exercise
Enriched cages provide some perches but often at insufficient height or number
Free-range and aviary systems significantly reduce fracture prevalence

Welfare Considerations

Osteoporosis in laying hens is caused by calcium depletion during egg production combined with insufficient exercise. Bone fractures cause chronic pain and are rarely detected or treated in commercial settings. Perch access is a low-cost, high-impact welfare intervention.

What You Can Do

Choose eggs certified to higher welfare standards with perch access
Support cage-free legislation that mandates enrichment
Advocate for fracture monitoring and vet oversight in laying hen facilities
Reduce egg consumption or choose plant-based alternatives
