Actually it isn't just about semantics. Turkeys are extremely closely related to the point that all but the Ocellated turkey belong to the same haploid group. The Ocellated turkey is a separate species and all other turkeys are the same species (Meleagris gallopavo) and differ only in the subspecies. All domestic turkeys are descended from the wild turkey (Meleagris gallopavo gallopavo).Breeds or varieties, it is all just a matter of APA semantics. I would pick one breed / variety and go with it a few years. I raise Blacks. Turkeys take up a lot of space so it is difficult to do well if you have a number of different kinds & you are wanting to improve your specific breed. I TRY to avoid sibling pairing just like I do in chickens.
