with rare breeds such as this, sometimes hatcheries are all you can find with them. Just bare in mind, like it has already been said, a good hatchery bird is very rare any more, most just want numbers and could care less of quality. If you look they all have some little disclaimer in there somewhere about " being true to breed", well some arent even that in my experience. But in laymans terms, that means this is a junk , mass production bird in most cases with no quality control over the breed.
Personally, I wouldnt waste my time with them, there are always reputable breeders out there who care and try their best to preserve the breed threw careful and select breeding.
Those are the ones I'd try to find.
You'll pay more, but to start with quality, verses years of trying to correct dozens of flaws, well worth the extra money in my opinion, actually cheaper if you figure in all the time, work, feed, and years of keeping and striving to correct.
And, yes, you hit the nail on the head with the crevies, so many people dont know what a true one is supposed to really look like, that black polish or crosses of the two often get brought into the breed and ruin the qualities of the birds. Watch for that and remember all the things in the breed standard I posted earlier.
Remember, all red facial skin and ear lobes!! Otherwise, it has polish in it
