Enriched colony cages attempt to improve on conventional battery cages for laying hens, but welfare outcomes vary significantly based on design and management.
Enriched colony systems represent an improvement over conventional battery cages but fall short of truly meeting hen welfare needs. While they provide some behavioral opportunities, the confined design still restricts natural locomotion, social dynamics, and full expression of motivated behaviors like foraging and dust bathing. Keel bone fractures — extremely painful injuries — are paradoxically more common in enriched colonies than conventional cages due to poorly designed perch systems. Floor-based systems and aviaries, while presenting their own management challenges, generally provide superior welfare outcomes when well-managed.
