Beak trimming causes acute and potentially chronic pain in laying hens and is practised as a response to underlying husbandry problems.
Beak trimming is a welfare compromise that treats the symptom of barren housing rather than the cause. While it reduces the severity of feather pecking, it causes its own welfare harm. The correct solution is to improve housing conditions, enrichment, and management so that the motivation for injurious pecking is reduced without the need for mutilation.
