Beak trimming of laying hens prevents injurious feather pecking but causes pain and alters normal beak function, representing a welfare trade-off.
Beak trimming represents a difficult welfare trade-off: preventing the welfare harm of feather pecking by causing the welfare harm of beak alteration. The welfare-preferred solution is to address the causes of feather pecking through better management, enrichment, and slower-growing strains rather than mutilating birds to tolerate poor conditions. Countries that have banned beak trimming demonstrate it is achievable.
