They are going to be EEs. Ameraucana chicks are going to run $6-10 each and very unlikely that any feed store would carry them.
As far as I know, the only way that you get a pure Ameraucana is from a breeder. The feed store (hatchery) chicks are EE's. My feed store has EE's listed as Ameraucanas, and has a little blurb about them on the front of the brooder that they're in, which is the same blurb that the hatchery has on their website (it's Belt hatchery). It says something about how they are known as 'the Easter Egg chicken' and they lay green, blue, pink, or brown eggs. A true Ameraucana doesn't lay the pink or the brown. Also I've seen lots of pictures of EE's with puffy cheeks, they are so cute! Unless I'm mistaken I think that EE's are Ameraucana mixes (I could be wrong). I definitely want to get a couple of EE's, I think they are adorable and from what everyone I know has said that has them, they are generally super friendly, too.
Ask the feed store where they got the chicks, if they came from a hatchery they're probably EE's. EE's do have often have fuzzy cheeks. EE's are an Ameraucana mix and the names Ameraucana, Americana, Araucana are often used as a marketing tool but if you read carefully the verbiage on the hatchery sites you'll see some kind of disclaimers that show that they are not pure Ameraucana or Araucana but 'easter eggers'
