I live in a neighborhood that is a very large circle. One way in and one way out. About 4½ miles. I ride the circle on my tractor from time to time just to look at the neighborhood. During my rides I see lots and lots of what I think are Game Chickens. Some are caged, some are just running the neighborhood loose on the back side of the circle. Can game hens be kept with normal hens (I know, I know, whats normal right?) or will they fight.
