Ideal Poultry in TX sells EE as Ameraucana and has for quite some time. This has lead to a pretty pervasive misunderstanding in most feed stores and backyard keepers in TX about the differences.
I’d search out a breeder that actually shows. There’s quite a few breeders in TX, some may be a short drive but worth it.
Also, these people have some nice birds But don’t breed what you’re looking for but DO raise what you want from hatchery stock. Anyway, they may be able to point you to someone in DFW that breeds true Ameraucana OR they order and grow out from hatcheries they can include some for you on a future order so you can get your hands on some without dealing with minimums.
