Now 13 weeks old. Still think cockerel? Not much comb or waddle has formed.
I don't recognize the feather pattern.. columbian maybe?
Comb and waddles are usually getting redish on mine by that age and I agree they look small. My GLW & SLW cockerels both had waddles that big by 8 weeks old.
Saddle feathers should be coming in by now. From these views I would say female. But can you post a side view showing the saddle to confirm?
