It was already mentioned, check out your breeder. If this person only has one pair of birds and knows next to nothing about them then she probably doesn't really know what constitutes a show quality bird.
I don't know if anyone made this point or not, just because the birds are show quality does not mean the chicks they produce will be any where near show quality.
Begin to rethink the direction you need to go in. If you are just wanting a pair of Silkies there are reputable breeders out there that can sell you birds they don't want to use in their breeding programs for a very reasonable price. There are Silkie breeders in E. TN. Some are absolutely the best people, others are questionable. Just like happens any where in the world.
