Ameraucanas are a real breed, Easter Eggers basically conform to the Ameraucana standard except for their assorted colors (very rarely do you get one that conforms to a color standard), and the fact that they sometimes lay brown eggs. But size wise, and body type, they are very close (depending on your source).
Even some "pure" strains of Ameraucanas lay a green egg, especially those that are still in developement. Not all Ameraucanas, or even Araucanas for that matter, lay blue eggs. Some are blue, some blue-green, and some green.
