Beak trimming in laying hens prevents injurious feather pecking but itself causes acute and chronic pain — making it a welfare trade-off that highlights the need for system changes that eliminate the root causes of pecking behaviour.
Beak trimming presents a genuine welfare dilemma — it causes pain to prevent a potentially more severe welfare harm. However, it is important to recognise that beak trimming addresses a symptom rather than the cause of injurious pecking. Root causes including high stocking density, poor lighting management, inadequate enrichment, nutritional deficiencies, and genetic factors can be addressed to reduce pecking incidence to levels where intact-beaked flocks are manageable. Progressive farms in Scandinavia and elsewhere have demonstrated that intact-beaked laying hen flocks are commercially viable. The welfare goal should be elimination of beak trimming through system improvement, not indefinite acceptance of the procedure.
