Since the bird in question is not one of the accepted colors for Ameraucana, is not muffed or bearded, it can not be an Ameraucana. It's an Easter Egger. They are not the same thing.
Actually she is a brown red Ameraucana. That is an accepted variety.
That's not Brown Red. Brown Reds have the same coloring as a Black Copper Marans. Hens are black with some brown, red, or gold in the neck and chest; nowhere else. The lack of muffs and beard are enough to show that she isn't Ameraucana, though.
