Americanas or Easter Eggers
Featured Stories on BackYard Chickens
Those are Easter Eggers. (ETA: at least look to be from the photo...can't see beards/muffs clearly, but I think I see some).
A true Ameraucana would lay blue eggs only, have slate/willow legs, beard/muff and has to be one of 8 standard colors.
Your birds are not of standard color and lay green eggs which means they are a hybrid from an Ameraucana (beard/muff)...that means Easter Egger.
