The transition from conventional to enriched colony cages represents progress but not the full welfare improvement that free-range systems can provide. Understanding the differences helps consumers choose effectively.
Enriched colony cages represent genuine improvement over conventional battery cages — hens can express some natural behaviors — but fall significantly short of free-range standards. The space allowance per hen in enriched colonies is still highly restrictive. Wing-spreading, full dust-bathing, and extended foraging are severely limited. Free-range systems allow full expression of natural behaviors but introduce risks from pecking, disease, and predation that require management. Welfare science consistently finds free-range systems superior on multiple measures when well managed.
