X2No offense, but the OP's bird doesn't look to have any Ameraucana or EE heritage. Those are pics of the parents and neither one is an Easter egger or Ameraucana. Plus, her chick has yellow legs and looks to have a straight comb. It's simply a mixed breed chick.
Juvenile plumage can be misleading, lots of chicks look similar at this point but feather out differently as they mature.
