I know they are hard to tell the pullets from roo's. My question is when do they start to get their combs? I have a white silkie chick who is about 9 weeks old. I got it from the feed store, so probably from a hatchery and not the greatest quality. Anyway it still doesn't have a raised comb at all, not even a bump. It has the most crazy top hair, like a white "Buckwheat" . Sometimes it seems like a roo and sometimes it seems like a pullet. I am trying to get new pictures. I am wondering when they normally start getting combs? I saw on another thread where someone had 6 week old silkie chicks and they had combs started already.
