She had chipmunk style chick fluff. Now she is developing a golden head. Rest of feathers still chick-like at six weeks--non descript black brown mix. Her legs are willow green. Sh does not have muffs or feathered wattles or feathered legs. Her comb is small. Maybe a pea comb. She is my rare exotic free chick from McMurray. Thanks for your guesses. alternatively she is an ameraucana and the free chick is single combed with black face, beard and muffs, slate legs, and black and red striped feathers resembling a brindle coat on a dog. I know one of these is an ameraucana. Thanks!
