Anything with parents who the genes for or laid blue eggs, but doesn't fit the breed standard for Am's or Araucanas is an Easter Egger. And, while each person may have their opinion on where the boundary is between Ameraucana and EE is, the most definite and agreed thing is that if it has disqualifying characteristics, it's an Easter Egger.
(green legs, yellow soles, lack of beard/muffs, presence of tufts)
