From Ideal, I would say it's an EE. It doesn't appear to have muffs/beard tho, but the leg color seems to fit and the plumage can be any color. I bet she'll be really pretty when she fills out completely. You'll have to post more pics as she grows.

Buff Ameraucana is a variety of ameraucana, however it depends on where you got them to know if it is a pure ameraucana or not.
I can tell that Hailey's is an EE - purchased from a hatchery and ameraucana do not have green legs
kesta - not sure on yours as it looks like the leg color is...
