Turkeys are the second most commonly farmed poultry species globally, with production concentrated in North America and Europe. Like broiler chickens, commercial turkeys have been selectively bred for rapid growth and large breast muscle, creating welfare challenges that parallel but exceed those of the broiler industry.
Genetic Selection and Welfare Consequences
Modern commercial turkeys have been selected for body weights that their skeletal and cardiovascular systems cannot adequately support. Males (toms) reach market weights of 20kg or more — so top-heavy that many cannot mate naturally, making artificial insemination the universal practice in commercial turkey production. The extreme muscle-to-skeletal ratio creates leg problems similar to broilers but at even greater severity; leg disorders are the most prevalent health and welfare problem in commercial turkeys.
Respiratory problems from the compressed thoracic cavity and the high oxygen demand of extreme muscle mass cause welfare compromise analogous to ascites in broiler chickens. Heart failure and sudden death syndrome occur at significant rates in fast-growing turkey strains.
Behavior and Enrichment
Turkeys are behaviorally complex birds. Wild turkeys have extensive home ranges, complex social structures, and sophisticated vocalizations. Commercial turkeys retain behavioral motivations for foraging, social interaction, and environmental exploration that are poorly met in intensive housing. Provision of environmental enrichment — straw bales, perches, pecking objects — reduces injurious pecking behavior and supports positive welfare behaviors.
Turkey poults (young turkeys) are particularly susceptible to welfare problems including chilling, starvation from failure to find feed and water, and injurious pecking. Early husbandry in the first two weeks of life is critical for poult welfare outcomes.
Beak Trimming and Injurious Pecking
Feather pecking and cannibalism in commercial turkey flocks cause significant welfare harm to victims. Beak trimming — partially removing the beak tip — reduces injury severity in pecking incidents. As with beak trimming in laying hens, beak trimming causes acute pain and potential chronic pain, representing a welfare compromise made to prevent worse welfare outcomes from injurious pecking. Environmental enrichment and stocking density management that reduce pecking motivation are preferable alternatives where practically achievable.
