Beak trimming of laying hens reduces injurious pecking but causes pain and welfare concerns that are driving moves toward higher-welfare alternatives.
Beak trimming is a welfare paradox: it is performed to prevent the welfare harm of injurious pecking, but causes pain in its own right. Infrared trimming, now the most common method, reduces but does not eliminate welfare costs. Research shows that behavioural indicators of chronic pain persist in trimmed hens for weeks. The deeper issue is that injurious pecking is a symptom of housing and management conditions that frustrate natural foraging behaviour. Addressing root causes through better enrichment, lower stocking density, and improved light management is preferable to surgical intervention.
