I have 12 RIR's that are 3 weeks old now. The combs on some of them are growing taller and getting very thick and have an orange tint to them. I have one that is a real pill and am getting more and more convinced everyday is a roo. His comb is one of them that is getting thick and taller. Does this mean that the chicks whose combs I have described are roos?
Some of them still have a short comb. Just curious!
