Okay - so we're supposed to just give up on these "fake rare breeds?" It took me nearly three years to find Nankin Bantams. Even the hatcheries ran out before they finished their orders ... and some of those that came through aren't as pure as the hatcheries want you to believe. They're crossed out, or at the very least, bred without careful selection, in order to multiply numbers ... and profits ... quickly. I got very lucky and finally found someone who was dedicated to preserving the breed.
As far as hatcheries selling rare breeds, look closely at some of the stock - not the stock photos, the actual stock - that comes from some of these mass-produced birds. The "Sultans" that most of the hatcheries are selling are bantams - not the true Sultan chicken. And the Sebrights. Have you seen some of the Sebrights from the hatcheries? Someone there got hold of a few pairs and cashed in on them, like many have done with the Cemanis. There's cranberry "bleeding" all over the AC's combs and white flecks in their feathers. The rare breeds have suffered for all the "attention" the hatchery mass production has given them.
I'm not trying to "bust" on anyone, here, and I'm not saying don't buy from the hatcheries. By all means, if you find a rare breed at a hatchery and can give it the attention needed for careful breeding, then do it! Hatchery chicks, while not always the best option, can be the only option for some people. Think of them as a good starting point for your own careful breeding program - and work to improve them from there.
Just remember that responsible breed conservation is important if we are going to save any of these truly rare breeds. Start with the best you can find, and move forward from there.
And if it helps any to know - The Livestock Conservancy updates the priority list every year. Their methods are outlined on the website. No "fake birds" there!
