I think it's a roo. 11 weeks, right? Too young for saddles really - I have 11 week old roos and they aren't even that red in the comb and haven't gotten their saddles in yet either. Part the feathers on the rear and see if you see any shinies coming in. :)
^^This. I didn't even think of looking at Donna. :P
But yes, with the big red comb and wattles I'm pretty sure you've got a cockerel there. And like featherz said, 11 weeks is too young for finding obvious saddle feathers.
