Our first barred rock turned out to be a cockerel, so I was very worried about the second one we got 6 months later. Her comb seemed to be turning pink compared to the two sex links we got at the same time and she appeared to have some characteristics of a cockerel, so I worried for about 7 weeks and with no further change in comb color or other progression of possible cockerel traits, I was certain she was a pullet. I've only had experience with these two barred rocks, so maybe someone else knows if their combs usually tend to be a little pink after the first couple of days. I know it certainly varies between show-quality and hatchery chicks.
