The breeds you are asking about fall under the "Heritage Breeds" label in the US, and they are getting very hard to find. There has been a push by some smaller farms to revive these breeds, but demand for them is just not strong.
As I understand it, most turkeys here are broad-crested whites that have been bred to be big, fat, and have a lot of breast meat. They are also cheap, which makes them so popular.
Hopefully someone here has experience with the Heritage breeds, but most of us have grown up eating the basic "utility" turkey.
