Think frizzle Cochin (mottled or black cockerel in first photos) was a MUCH larger egg and is much larger than all of the others hatched out within the same week. We hatched bantam silkies, mille flour d'uccles and frizzle cochin or sizzles or sizzle sultans --supposedly. Bantam frizzle ( white or calico pullet in second group) and not sure if Bantam or standard or if Cochin or sex (black smooth feathering in last set of photos) this chick is also a bit larger than the others -but smaller than the chick in first group of photos. ALSO this chick has black skin and FIVE toes like the silkies. funny looking chick. Very precocious too. Trying to fly out of the space I have them in--more energetic like my mille Fleur d'uccle chicks. ALL three of these Chicks hatched the 19th of Feb. and came from same place. so 3.5 weeks old. photos are from day of hatch, at two weeks old and at three weeks. Thanks!
