Hen Welfare in Enriched Cages: Evidence and Debate

Enriched (colony) cages represent a compromise between battery cages (now banned in EU) and cage-free systems, but welfare debates continue about whether they adequately meet hen needs.

Key Facts

EU battery cages were banned in 2012 and replaced with enriched colony cages providing at least 750 cm2 per bird
Enriched cages include perches, a nest box area and scratch pad, unlike barren battery cages
Research shows hens in enriched cages have lower rates of feather pecking and bone breakage than cage-free systems
However, space allowances are still very limited - hens cannot fully spread wings, run or dust bathe properly
Some countries (Switzerland, Austria, Germany) have banned enriched cages entirely in favour of cage-free systems

Welfare Considerations

The enriched cage debate reflects the genuine complexity of farm animal welfare trade-offs. Cage-free systems enable more natural behaviours but can have higher rates of feather pecking, keel bone fractures and disease. Enriched cages reduce some of these harms but fundamentally restrict the space and freedom that hens need for many natural behaviours. The welfare science community increasingly concludes that well-managed cage-free systems with adequate enrichment, lower densities and good stockmanship provide better overall welfare than enriched cages - but the 'well-managed' qualifier is critical.

What You Can Do

Choose free-range or organic eggs from farms with credible cage-free welfare standards
Advocate for policies phasing out enriched cages in favour of well-managed cage-free systems
Support research into management practices that reduce welfare problems in cage-free housing
Ask your preferred egg supplier what welfare improvements they are implementing
