Beak trimming or infrared beak treatment in laying hens and turkeys is practised to prevent injurious pecking — but it addresses the symptom rather than the cause, and causes welfare harm.
Beak treatment is a welfare compromise: it reduces injurious feather pecking — itself a serious welfare problem — at the cost of causing pain and permanent functional alteration of a highly sensitive organ. The beak is rich in nerve endings and used for feeding, exploration, and social interaction. Treatment, even with infrared technology, causes acute pain and potentially chronic sensitivity changes. The best welfare outcome is intact-beak production enabled by adequate enrichment, lower stocking density, and appropriate strain selection. Countries that have achieved this demonstrate it is possible; the industry must be pushed to replicate this progress.
