Commercial turkeys are among the most welfare-compromised farmed animals. Intensive selection for rapid breast muscle growth has produced birds unable to walk properly, mate naturally, or live without chronic pain.
Commercial turkey welfare represents a case study in how breeding for single production traits creates systematic animal suffering. The modern broad-breasted white turkey's muscle mass exceeds what its skeleton and cardiovascular system can support — birds spend much of their time sitting because walking is painful. Heart failure, leg disorders, and skin lesions are endemic. The inability to mate naturally means every commercial turkey comes from artificial insemination, a stressful procedure applied to all breeding birds. Beak trimming, performed to control injurious pecking caused by crowding and frustration, is itself painful and impairs feeding behavior. Heritage turkey breeds maintain natural proportions and behaviors but are commercially marginal. Meaningful welfare improvement requires either selecting for slower-growing genetics or dramatically reducing stocking density.
