Enriched Colony Cages for Laying Hens: Welfare Assessment

Enriched colony cages replaced conventional battery cages in the EU but remain controversial. An honest welfare assessment helps consumers and advocates understand the trade-offs.

Key Facts

Conventional battery cages were banned in the EU in 2012, replaced by enriched colony cages
Enriched colony cages provide 750 cm2 per hen, a nest box, perch, and scratch area
Hens in enriched colonies still cannot spread their wings, take a dust bath effectively, or engage in normal ranging behavior
Bone strength is improved over battery cages due to perches and slightly more movement
Barn and free-range systems provide substantially better welfare but face different challenges including disease and pecking
Consumer preference in many markets is shifting toward cage-free systems despite higher costs

Welfare Considerations

Enriched colony cages represent an improvement over battery cages but fail to meet the welfare needs of hens adequately. Hens retain strong motivations for behaviors — dust bathing, foraging, perching at height, nesting in seclusion — that are still frustrated in enriched systems. The enrichments provided are insufficient in space and quality for the number of birds using them. The honest welfare assessment places enriched colony cages as an incremental improvement, not a welfare solution.

What You Can Do

Choose free-range, barn, or RSPCA Assured eggs over enriched colony or conventional cage eggs
