There is no such thing as a "recognized breeder" of Ameraucanas. There are breeders out there who have worked their butts off and are well known because they have quality stock. But that's not the same thing at all. There is a list of breeders that the Ameraucana club maintains, but you have to be a member and you have to ask to be listed. Just because someone isn't listed as a breeder with the Ameraucana club does not mean that they aren't breeding Ameraucana or that their birds are somehow EE.
And no, the APA does not use "recognized breeders" as a point of judging. Ameraucanas are judged exactly the same as any other breed in an APA show, judged on how they physically match the written standard of perfection. There is no place on the entry form or the cage card to list what lines the bird is from or what breeder the bird came from. Thus there is no way for a judge to know whether a bird came from a well known breeder or someone who they've never heard of.
I had a purebred Ameraucana rooster and among my flock of 6 hens one of them is a purebred Ameraucana hen. Any chicks produced by that rooster and the purebred Ameraucana hen ARE Ameraucana, not EE. Unfortunately, the egg color of my Ameraucana hen is not the best. In fact, it's pretty much the exact same shade of green as my hatchery EE hen. So, I had no way of knowing which of the green eggs that hatched were true Ameraucanas and which were EE. For that reason, and that reason alone, I sold all of the chicks as EE because more than half of them were EE in the truest sense of the word (in addition to the eggs from my Ameraucana and EE there were also about a half dozen Sussex-Ameraucana and one that I strongly suspect was from my Orpington hen).
