I'm really curious if this chick is a pullet or cockerel. It's a little over 3 weeks old now and really feathering in. When I got her/him at 1 week, I picked out one of the darkest of the group... it had a lot of black fuzz then. It's head is getting lighter, but the comb is not noticeably growing and staying yellow. The legs are not heavy and don't have much dark wash, but neither did any of the chicks in the group. I'd really appreciate hearing any of your opinions! These 3 pics at 3 weeks... Here is the chick now at 5 1/2 weeks. The neck feathers really look "laced" now instead of barred. Very pretty. I agree... must be a barred rock mix. Still hoping for a hen! What do y'all think?
