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.
