If you have to ask the question.. then it's very likely an EE.
Ameraucana will ALWAYS be sold under their color variety... blue, black , wheaten, red brown, silver, etc...
As mentioned above they will also not be sold in the $3-4 price range... but usually around $20... Noting I have purchased from several reputable breeders... and they often sell their chicks are $6 for bantams and $10 for large fowl.
