Hen Welfare in Cage-Free Egg Systems

The transition from conventional battery cages to cage-free egg production represents a significant improvement in hen welfare, while cage-free systems still have important welfare challenges to address.

Key Facts

Battery cages confine hens to 67 square inches - less than a letter-size piece of paper
Cage-free systems allow hens to walk, spread wings, and access perches and nest boxes
Keel bone fractures affect 50-80% of hens in cage-free systems from falls and collisions
Pecking behavior and cannibalism remain significant challenges in cage-free flocks
Air quality and dust exposure are welfare concerns in poorly managed cage-free facilities
Enriched colony cages provide more space than conventional cages but less than cage-free systems

Welfare Considerations

Battery cages prevent virtually all natural hen behaviors including spreading wings, dust-bathing, perching, and nesting. The profound behavioral deprivation causes frustrated, repetitive behaviors and chronic psychological suffering. Cage-free systems allow expression of these behaviors but introduce new welfare challenges including keel bone injuries from collisions with perches and falls, and increased aggression in large flocks. Well-managed cage-free systems with appropriate stocking density, perch design, and management represent a genuine welfare improvement over cages.

What You Can Do

Choose cage-free, free-range, or pasture-raised eggs to support higher welfare egg production
Look for third-party welfare certifications that verify cage-free conditions meet standards
Support corporate commitments to cage-free sourcing from food companies and retailers
Advocate for retailer and food service completion of cage-free commitments
Reduce egg consumption or transition to plant-based alternatives to eliminate hen welfare concerns
