I know absolutely nothing about the game breeds, but I do know some breeds the roosters are what they call "hen feathered". If I just saw that face I would say definite rooster. Maybe someone who knows these breeds better can tell you.
yep its a hen. hens crowing or hens with spurs are not that uncommon in birds with game ancestry. by her comb she is not a junglefowl though, that and the fact that if you're in the U.S. feral populations of red junglefowl are not exactly common...
Definitely game something or other; definitely a hen. Hens do occasionally crow--some regularly, some occasionally. I used to have a silkie hen that crowed now and again. I know someone with a campine hen who crows regularly--usually just after she lays an egg!
Any breed could escape and become feral--my understanding is that that is how the Key West and Kauai wild chickens began.
I don't even know what kind of comb that is--definitely a bit different
