ameraucanas are easter eggers, but only some easter eggers are ameraucanas. there are breed standards for true ameraucanas. however since there are so few breeds that do green or blue eggs, a lot of feed stores and sellers label all peeps that are crossed with amers as if they were true, so you can't always trust the label. this year my husband bought 4 amer pullets from the feed store, and the vendor said the eggs might be tan, pink, or turquoise... to me that means they are actually a wider ee cross but he was selling them as amer.
doesn't matter a whole lot to me, but if we wanted to file them with the ameraucana breeders club, they would have to have all the correct characteristics to qualify. (looked it up just a few days ago!)
