Beak trimming in laying hens prevents injurious pecking in commercial flocks, but the procedure itself causes acute and chronic pain — driving research into breed and management alternatives.
Beak trimming is a welfare compromise — preventing the severe harm of injurious pecking by causing moderate procedural harm. Neuroma formation after trimming causes chronic pain in a proportion of birds. Better solutions exist: enriched housing with perches, litter, and foraging opportunities reduces pecking motivation. Low-density flocks in appropriately managed environments can be maintained with intact beaks. The goal should be eliminating the conditions that require trimming.
