Looks like an EE girl to me. Probably more mixed blood than ameraucana due to lack of muffs/beard. Green legs are a pretty good sign of a cross though, so I agree it's an EE.
I say pullet also, looks like it definintly has game in it. I will post a pic of my standard games soon as I can, but yours look alot like my game girls.
most EE's follow the Ameraucana standard except for color pattern and egg color, they nearly always have the right (pea) comb and muffs/beard. Even hatcheries have standards.
