Commercial turkeys have been selectively bred to grow so rapidly that serious health problems are common, mirroring and in some respects exceeding the issues seen in broiler chickens.
Commercial turkey welfare suffers from the same fundamental genetic compromise as broiler chickens — birds bred for growth rates their bodies cannot sustain. The additional requirement for artificial insemination due to physical inability to mate naturally illustrates how far commercial turkey breeding has departed from biological functionality. Heritage and slower-growing breeds that can live more normal turkey lives represent a genuine welfare improvement, though at significantly higher production cost.
