I don't know, it still looks girly to me. I would really be expecting more comb/wattle development or at least red color in a male at 10 weeks, and still more of the stork look, it could just be a slow developing fast feathering male. I am more familiar with light brahmas, and I can't get that good a look with those pictures, but those feathers just look like regular buff feathers coming through, I am not seeing the pointy saddle / neck feathers or that darker more red color the males get.... yet ... well, good luck and hope it is a girl ...
