Enriched Colony Cage Welfare in Laying Hens

Enriched colony cages replaced conventional battery cages in the EU in 2012, but welfare outcomes compared to barn and free-range systems remain debated.

Key Facts

Enriched cages provide 750cm2 per bird with nest box, perch, and scratch area
Battery cages were banned in EU from January 2012
Enriched cages provide more space and resources than battery cages but restrict movement
Feather pecking incidence is generally lower in enriched cages than free-range
Consumer pressure is driving retailer commitments to cage-free sourcing

Welfare Considerations

Enriched cages prevent some natural behaviours including wing-flapping and extended foraging that hens are highly motivated to perform. Dust bathing in the small scratch area is behavioural but lacks the full dust bathing functionality of loose litter. Cage-free systems allow more natural behaviour but can have higher mortality from feather pecking and disease pressure if poorly managed.
