Beak trimming is performed on laying hens to prevent feather pecking, but it causes acute and chronic pain. Understanding the evidence supports welfare-positive alternatives.
Beak trimming is a painful procedure performed to prevent feather pecking — itself a welfare problem caused by inadequate management. Both the trim and the underlying cause of feather pecking represent welfare failures. Modern infrared trimming causes less acute pain than historical hot-blade methods but may still lead to chronic beak sensitivity. Countries that have banned beak trimming manage feather pecking through enrichment, lower stocking densities, and breed selection for reduced pecking tendency. Addressing root causes rather than trimming treats the symptom while leaving the welfare problem intact.
