what is a game fowl?

what is a game fowl? My opinion is it's in his name it's a bird that was bred for gamness above all else if it's game and was bred to be game then it's a game fowl if it's not game call it dinner In st. thomas a game fowl was a breed, it had nothing to do with color or how well the fowl fight, there was a physical make up of the fowl and yes a game fowl was fearless in battle now with that said you could also have crosses of game fowls with common yard fowls that was fearless in battle and would win against a pure game fowl but to us that was not a game fowl no matter how well it fought, here in the U.S there seems to be a different idea of what a game fowl is, it seems to be if a fowl could win in a pit it is a game fowl. so i am am asking my fellow cockers to explain what is a game fowl so i can understand, i think that the fowl must first pass the physical appearance of what a game fowl should look like then is must preform like a game fowl should it should fight and not run, no matter how beat up it gets it will continue to fight until it dies, so how do you determine if a fowl is a game fowl, it cannot be by its performance in a pit, a game fowl is a breed not a performance
