Hen Welfare in Cage-Free Egg Systems

Cage-free housing provides hens more freedom than battery cages but introduces new welfare challenges that require careful management.

Key Facts

Cage-free systems allow hens to walk, spread wings, and perform some natural behaviors
Mortality rates in cage-free flocks can be higher than in enriched cages
Keel bone fractures affect up to 80% of hens in some cage-free systems
Multi-tier systems require hens to navigate vertical spaces safely
Litter quality management is critical for respiratory and foot health in cage-free

Welfare Considerations

The transition from battery cages to cage-free systems represents genuine welfare improvement in some respects but introduces new challenges. Cage-free hens can perform more natural behaviors but face increased risks of injurious pecking, smothering, and keel bone fractures from perch access. Well-managed cage-free systems with good lighting, enrichment, appropriate flock sizes, and monitoring can achieve better welfare than poorly managed ones. Consumer and regulatory pressure for cage-free must be accompanied by attention to management standards.

What You Can Do

Choose eggs certified to cage-free standards with audited management criteria
Ask egg producers about keel bone fracture rates and management practices
Support further welfare improvements beyond cage-free including enriched environments
Advocate for welfare outcome standards not just housing type specifications
Consider reducing egg consumption or choosing plant-based alternatives
