The way I understand it from here and other sites, in order for a 'breed' of chicken to be officially recognized as such, the off spring of like parentage must breed true, meaning the offspring will maintain similar traits, at least in a certain percentage of the off spring. Am I right so far? Now if I'm still correct, an Easter Egger is any off spring of any 'blue' egg layer and any 'other color' egg layer, OR the offspring of two Easter Eggers, creating off spring that may or may not have the characteristics of it's parents and could lay a variety of different colored eggs, as opposed to all off spring laying the same color, with only small variations of tint or hue.The origins of all the blue egg layers are the Quechua, from South America. This thread is quite thorough in talking about the history of the breed: https://www.backyardchickens.com/t/402512/quechua-tojuda-ameraucana-easter-eggers-in-vino-veritas
In short, they came from South America, were exported around the world and crossed with all sorts of breeds, were brought to the U.S. and refined into a few different breeds. Remember, with chickens it's not so much that the parents are "purebred" as the offspring follow the standards of the breed. That's why you can have two purebred Ameraucana or Araucana and when crossed together, the offspring might not qualify for the breed (in the case of two colors being mixed that don't match the standard, or off-colored legs, or what have you). Of course, the longer you breed a line for a certain standard, the more likely you'll keep getting that standard with each generation, which is how you get a "breed".
The thing with Easter Eggers is that they're a land race (as someone else explained earlier) which means as long as they look generally alike then they still fit in with other Easter Eggers. The part that's confusing is that a lot of the traits that define an Easter Egger, fluffy cheeks, green legs, blue eggs, are dominant traits and are therefore spread to their offspring widely, making half-breeds look a lot like an EE so they're still called EE.
The other thing is that by default, any Araucana or Ameraucana that doesn't meet the standard is an Easter Egger since they fit into the "land race" description.
Clear as mud?
As for the accusation of deliberate deception, if the hatchery actually calls their EEs Ameraucanas or Araucanas using the correct spelling then there is no argument; it is being done to defraud the buyer. However who is to say the particular hatchery doesn't use the word Americana, Americauna or some other mis-spelling of the breed name spelling because their particular EEs were actually bred from one of those true breeds? If the buyer has enough knowledge about the actual breeds, would they really be stupid enough to be fooled by an obvious misspelling?

Unless the accuser actually works with or is in some other way legally connected to the hatchery, then their accusations of deliberate fraud are little more than libel.
Regardless, even the loudest rantings of an amateur poultry newsgroup is not going to change this practice. But to avoid further rantings I will use "Easter Egger" or EE rather than my preferred Americana.
BTW, by definition, any artificially created breed can be called a 'land race'.
