I have 4 little fuzz butts I hatched in an incubator about a week ago. I ended up with 1 FBCM, 1 BLCM, 1 CM and 1 Blue Orpington. Now at 1 week the FBCM and the CM have big combs. The BLCM and BLO, not so much. I'm thinking I have a split in the sexes with the FBCM and CM being roos. I'll try to take picts tomorrow. Can you really tell this early? It's fine if I have one or two roos, I just would like to plan.
