Those roos are easter eggers. Not true Ameraucana's. Ameraucana's lay blue eggs. Check out the Ameraucana Breeders Club webiste for descriptions and such.
Araucanas don't look anything like either ameraucanas or Easter Eggers. They are rumpless and have tufts. In the US they never have beards or muffs. Ameraucanas have tails, beards and muffs.
Araucanas and ameraucanas lay blue (not green, pink or olive) eggs. Easter eggers can lay just about any egg colour.
Your birds are Easter Eggers. I'll give you a quick description
Araucanas - SQ have ear tufts (different from muffs) and are tail-less. Have a pea comb. Suppose to lay blue eggs. Come in certain colors. Can be cleanfaced and tailed, but that means they are NOT show quality.
Ameraucanas - SQ have muffs, and tails. Have a pea comb. Supposed to lay blue eggs. Come in certain colors.
Easter Eggers - A mutt chicken - a cross between a blue egg laying bird (Ameraucana or Araucana) and any other breed of chicken (usually a great egg layer). They usually have muffs and a tail, and usually have a pea comb. Dont come in certain colors, seeing as they are mutts. They can lay any color egg, but usually lay green, sometimes blue.
I'm an Ameraucana Breeder. I would suggest doing a search on BYC for "Ameraucana" or even me as the "Author" and you will find a ton of info already been written.
