I can try to explain since I am one of the original breeders that helped create the breed . At that time anything that laid blue / green eggs was called Araucana . We chose tails and beards because of the lethal effect of tufts and the mechanical breeding trouble of no tail . We were told we would never get them into the standard as Araucana . We had a vote and chose Ameraucana as a name . We had to breed to existing colors . We chose the colors and created them . We had to distinguish them from the hatchery mutts being sold . We continue to struggle with the confusion 40 + years later as the hatcheries are calling their birds Americana (spelling) . A bunch of color crosses makes them really hard to tell from EE adding to the confusion . The club took the position of calling any color mixes EE . We get a bad reputation of being very picky because of this . There are several color projects out there . No new colors have been added to the standard in 40 + years . It is a huge undertaking to get them recognized . On top of that some projects have detractors within the club . I have one of those myself . I do not usually discuss them on this forum . I do not care to argue . I have invested a huge amount of time , money and effort into these . Breeders state what their project color is . Selling mixed colors as Ameraucana really complicates things .
