True Ameraucanas always have beards, muffs, pea combs, slate blue legs, and conform to SOP color standards. Any deviation from these is an Easter Egger.
They are Blue Ameraucanas. There is no such breed as Americana. Hatcheries often and incorrectly market their Easter Eggers, which are hybrids rather than a true breed, as Ameraucanas, sometimes intentionally misspelling it as "Americana."
