Hi Candace - I have a few Ameraucana hens, which I hatched from eggs and also have Easter Eggers, which I love.
My blue bantam Easter Egger (see below) is an accepted Ameraucana color, has slate legs, a pea comb, beard and muffs, lays blue (not green) eggs, but she is still considered an Easter Egger because I purchased her from a hatchery. Since she was not specifically bred to be 'blue', no telling what color her offspring will be. If a suspected Ameraucana does not breed true to color, that also disqualifies the suspected chicken to not be a true ameraucana.
