The only thing I can suggest besides Porters, who is very advanced in the color genetics etc....is get in contact with the American Livestock Breeds Conservancy. They did a big thing on monitoring Turkey breeds.
Hatcheries are what have kept the turkey breeds alive. I would not turn up my nose at them because most all are on the NPIP program and may be the only way to get some of the rarer colors and varieties. Also, try subscribing to the Poultry Press or at least try going online and see when there is a show in Tenn and maybe go to it and see what is available. However, breeders are few and far between and poults will only be available in the spring. Sometimes you can find some at some of the poultry swaps that are held. Also try the extension service in the area and the 4-H and FFA clubs.
