Farmed Laying Hen Welfare: Enriched vs Battery Systems

Enriched colony cages provide minimal improvements over banned battery cages; the science increasingly supports only cage-free and higher systems for adequate hen welfare.

Key Facts

The EU banned conventional battery cages in 2012 and replaced them with enriched colony cages
Enriched cages provide a minimum 750cm2 per hen, a scratching area, perch, and nest box
Studies show enriched cage hens still show significantly more frustration than cage-free hens
Keel bone fractures are as prevalent in enriched cages as in battery cages
Over 200 major food companies globally have made cage-free commitments for egg supply chains

Welfare Considerations

Enriched cages represent a welfare improvement over battery cages but fall far short of providing hens with meaningful behavioral opportunities. The nest box is too small for comfortable use, perches are minimal, and scratching areas are inadequate. Welfare science consistently shows that cage-free barn systems, while not perfect, allow substantially more natural behavior expression. The global corporate commitment to cage-free eggs represents appropriate recognition of this evidence.

What You Can Do

Choose cage-free, free-range, or certified organic eggs over enriched cage alternatives
Support retailers and food companies with clear timelines for cage-free transitions
Advocate for legislative ban on enriched cage systems following the battery cage ban model
Reduce egg consumption or shift to plant-based alternatives to avoid supporting any caged system
