Comparing enriched colony cage and free-range egg production reveals welfare trade-offs across multiple welfare domains, informing better consumer and policy choices.
The enriched cage versus free-range welfare comparison reveals that welfare is multidimensional and that no system is uniformly superior across all welfare indicators. Free-range provides behavioral freedom — space, outdoor access, dust bathing, nesting — that significantly improves welfare. However, keel bone fractures and higher mortality create welfare costs absent in more controlled cage systems. The welfare science consensus is that overall welfare is better in well-managed free-range systems despite specific disadvantages. However, poorly managed free-range (insufficient outdoor access, high predation, disease pressure) may perform worse than enriched cages. Consumer choice should therefore prioritize certified free-range with verified management standards.
