I suppose you could say Ameraucanas are Easter Eggers, but Easter Eggers are not Ameraucanas. Easter Egger is a generic term for a bird that carries the blue egg gene. Ameraucanas are a breed recognized by the APA--and to be an Ameraucana they must fit the Standard (description of bird, not size) and breed true. The chances that an Easter Egger purchased at a feed store fits the standard and breeds true is unlikely.
