We're at 10 weeks, too and waiting for a roo or two. We actually wouldn't mind one... I think? Ours are clucking more than they're peeping now as well. When do their combs and wattles really start to come in?
I have twenty eight, 12 week olds. I noticed a bright red comb starting on two of them at eight weeks.. I was suspicious... At nine weeks, one of them started to crow.... This morning (12 weeks old) the second one started crowing.
