comb size indicates...?

[keystonepaul]

If you have 10 chicks and as they grow 4-5 have noticablly quicker growing and as a result noticablly larger combs than the others is this any indication of them being a rooster or at less than 6 or 8 weeks old does it mean anything. Thanks, Keystonepaul

Have you noticed any red with those noticeably larger combs? If so, then they would be roos.

could be! my cockerel started showing definite signs of not being a girl at two weeks. it wasn't his comb at first, but his feathering that made me suspicious. after that, the comb and wattles appeared nearly overnight and were very dark pink. so, yes, much earlier than 6-8 weeks for sure.
