Easter egger: is a mix between an Ameracauna and another bird. It can also be a mix between an Auracauna(spelling?) and another bird. Easter Eggers come in any color you can think of and have only breed generalizations, although they're not really a breed. *most* have muffs and beards, green or willow legs, a peacomb and will lay green blue or even pink eggs. They are not recognized by any poultry association as a breed. Easter Eggers are generally friendlier, lay more often, and are les flighty than their pure bred ancestors. Many hatcheries will (whether on purpose or not) sell Easter Eggers as "Americana or Aracauna" although they are only Easter Eggers.
Ameracauna are pure bred birds with a peacomb, muffs and beards and black/slate legs. They only come in a very select few colors and will lay blue eggs. If they do not have all of these qualities, they are not considered true Ameracauna. The only place you can get pure bred Ameracaunas for the most part is from private breeders and not hatcheries. I know of one hatchery that claims to have wheaten Ameracauna, but I don't know the creditibility of that. You can check out the "Ameracauna scrapbook" for the acceptable colors they can come in.
Aracaunas are rumpless(tail less) birds with ear tufts. Ear tufts are different than muffs and although I don't know much more about them, I feel they only come in certain colors too. They also lay blue eggs.
