Show and breeder quality Ameraucana are indeed normal large fowl. Hatchery birds are - as you found out - Easter Eggers and often smaller.
A well bred Ameraucana has a lot of heft, lays a lovely largish egg and is totally differentfrom anything a hatchery produces. There's a man near me who breeds the loveliest wheaten ameraucanas, he could show except his disability limits him. But he's dedicated to the breed and it shows.
You'd have to ask the silkie show folk about a true weight range for show and breeder quality birds.
