The debate between furnished (enriched) colony cages and free-range systems for laying hens involves genuine welfare trade-offs. Understanding the evidence helps advocates make informed policy arguments.
The furnished cage versus free-range welfare debate is one of the genuinely contested areas in farm animal welfare science. Unlike many welfare debates where the evidence clearly points in one direction, this one involves real trade-offs: behavioral welfare is better in free-range; keel bone welfare and mortality may be better in furnished cages. Consumer campaigns for cage-free eggs have driven rapid free-range transitions that, without careful management, could result in welfare regressions in areas like keel bone fractures and feather pecking. This makes it one of the most important areas for ongoing research, careful communication with consumers, and management standards development.
