If a hatchery ...or anyone for that matter....spells Ameraucana any way other than "Ameraucana" ,it is not a pure bird, and is either an olive egger, or most likely, an Easter Egger.
There are only 8 colors in the APA standard and there are ohly a few colors being worked on, such as Colombian, Chocolate, and Lavendars like mine.
Easter Eggers, on the other hand, can come in any color, have any comb, any colored eggs, and any colored legs. While Ameraucanas have slate/dark/black legs, pea combs, muffs, a beard, and lay green-olive green eggs.
