Enriched Colony Cages for Laying Hens: Welfare Assessment

Enriched colony cages were introduced as a welfare improvement over conventional battery cages, but ongoing research reveals significant limitations in meeting hens behavioral needs.

Key Facts

Enriched cages provide 750cm2 per hen versus 550cm2 in conventional cages
Requirements include perches, nest boxes, and scratch areas
Studies show hens still cannot perform full wing-spreading in most designs
Bone fractures remain common due to limited exercise opportunities
EU ban on conventional battery cages took effect in 2012

Welfare Considerations

While enriched cages represent an improvement over barren battery cages, research consistently shows they still prevent many natural behaviors. Hens cannot establish stable social hierarchies, dust-bathe properly, or exercise sufficiently to maintain bone health. Welfare scientists widely advocate for cage-free systems.

What You Can Do

Choose cage-free or pasture-raised eggs when possible
Support legislation mandating cage-free systems
Ask supermarkets and restaurants about their egg sourcing policies
Donate to organizations campaigning for laying hen welfare reform
Educate friends and family about laying hen housing systems
