Modern commercial turkeys have been selectively bred for such rapid breast muscle growth that they cannot mate naturally, walk normally, or live without significant health interventions.
The welfare of commercial turkeys is compromised at a fundamental genetic level — the same traits selected for productivity have created animals whose bodies cause them chronic suffering. Leg disorders cause pain that affects mobility, feed access, and resting behavior. The inability to engage in natural mating behavior represents a severe restriction of species-typical activity. Beak trimming, while reducing injurious pecking, is itself a painful procedure that alters beak sensation long-term. High stocking densities frustrate social organization and increase stress. Heritage breed alternatives demonstrate that turkey production without these systemic welfare problems is commercially viable, albeit at higher cost.
