Beak trimming is performed on millions of laying hens annually to reduce injurious pecking in intensive systems. The practice causes pain and is widely considered a welfare compromise for a systemic problem.
Beak trimming treats a symptom rather than the cause of injurious pecking, which arises from inadequate housing, nutrition, and management. Permanent reduction of sensory capacity in the beak — a sensitive organ used for exploration and feeding — causes a lasting welfare deficit. The existence of beak-trimming-free systems in several countries demonstrates that it is not necessary when management standards are adequate.
