I am not aware of any non-game gamefowl. You might come close if you can get some feral birds from Florida or the Island of Kauai in Hawaii. The gamefowl have been selected in part, to thrive in close proximity to humans. All chickens are derived from crosses between jungle fowl species. Almost certainly the adaptions include being able to gamble on human activity providing protection. By human activity I mean structures and agriculture. Not all gamefowl are well suited for cold climates. Some have been selected for endurance under conditions of high temperature and humidity; Orientals follow that pattern.
