Enriched colony cages for egg-laying hens provide more space and some facilities compared to conventional battery cages, but welfare researchers debate whether they genuinely meet hens' behavioural needs.
Enriched cages represent a genuine improvement over battery cages — hens can lay eggs in a nest, perch at night, and scratch to some degree. However, the enrichments are often too small or poorly designed to be consistently used, and the fundamental restriction of movement remains. Hens cannot dust bathe properly, explore freely, or express full foraging behaviours. The nest boxes, often shared, can create competition and stress. Welfare science generally supports cage-free or free-range systems as superior for most welfare indicators, though flock size, management quality, and outdoor access quality matter enormously. Enriched cages are a transitional step, not a destination.
