I ordered a dozen barred rock bantams from Dick Horstman this spring - shipment had an extra chick. Chicks are about 4 weeks old. Dark legs - starting to develop a crest of some sort. Anyone have any ideas on breed/gender? 2nd from left in first couple of photos, middle in the 3rd. Also, since they're in the photo - I'm seeing 2 pullets and a cockerel from the barred rocks n the 1st 2 photos and a pullet/cockerel in the 2nd?
