I'm not saying you don't have true Amseraucanas but did you check if the match APA standerds? A lot of people sell chicks/chickens as Amseraucanas while they are really Easter Eggers.
Gold looks like a Buff Orpington, Peck looks like a Barred Rock (not a Dominique because it has a straight comb not a rosecomb), Nugget looks like a Black sex-link. They all look like pullets.
@Fuzzyrules if your "ameraucana" looked like Nugget then it isn't a Ameraucana, because Ameraucanas...
