Comparative welfare research across laying hen production systems reveals the genuine trade-offs between different approaches and helps identify what interventions improve hen welfare most effectively.
The comparative welfare research on laying hen systems reveals genuine complexity that resists simple messaging. Cage-free systems are welfare-superior overall - they allow more natural behavior including nesting, perching, and outdoor foraging - but they introduce welfare problems including keel bone fractures and higher mortality that enriched colony systems largely avoid. This is not a reason to oppose cage-free transitions, but it is a reason to invest in making cage-free systems work better - addressing perch design, lighting management, and flock management to reduce the welfare problems that cage-free systems introduce while preserving their behavioral welfare advantages. The welfare direction is clear: cage-free, with continuous improvement of the systems within that category.
