I've noticed a lot of hatcheries are just making up a name and selling chicks. Some are half breeds which will be vigorous but not breed true. It's extremely hard to get buff, wheaten and brown red ameraucanas now. So many people are breeding project colors and BBS genetics were so popular other types became rare. I think the popularity of the breed is also its downfall. It's taking me quite some time to rebuild my flock after a couple of disasters. Getting one quality Blue Wheaten roo was a couple year struggle. EE are fabulous birds for those who want variety in their flock and eggs, but the hatcheries have done a disservice to the ameraucana breed selling "americanas" when they are really Easter Eggers. Post pictures of what you have and I can tell you if they meet the standard.
These are the true ameraucana colors:
Black, Blue, Blue Wheaten, Brown Red, Buff, Self Blue , Silver, Splash, Wheaten & White
Muffs, beards, pea combs, right colored legs and body shape are considerations as well.
