Commercial turkeys have been selectively bred for such extreme breast muscle development that they can no longer breed naturally, walk comfortably, or thermoregulate effectively — creating systemic welfare failures across the industry.
Turkey welfare failures are largely built into the genetics of commercial breeds. The extreme breast muscle mass that makes modern turkeys commercially valuable causes chronic orthopedic problems — birds struggle to support their own weight, develop painful joint conditions, and have difficulty reaching food and water. Artificial insemination of all commercial turkey hens is a welfare issue in itself, requiring repeated handling and physical manipulation of both males and females. Respiratory infections spread rapidly through the dusty, ammonia-laden air of large sheds. The inability of these birds to exhibit any wild turkey behavior — flying, roosting, foraging, courtship display — represents a complete denial of their behavioral repertoire. Heritage breed turkeys, which can live and behave normally, offer a welfare alternative but represent a tiny fraction of production.
