The American Games was created from a variety of European and Eastern games.The American Game is an American breed of game fowl, chickens bred specifically for cockfighting. It has many color varieties, and may also be kept for ornament.
American Games are a gorgeous breed of chicken, but due to its highly aggressive nature sexually mature males must be kept separated. If left to free range or penned together, males will fight to establish dominance and due to their gameness, often fight to the death. If more than one rooster is kept, care must be taken to ensure the birds cannot reach each other.
Some of the more popular types are Hatch, Kelso, Albany, Sweater, Whitehackle, Claret, Roundhead, and Butcher. Species names come from people who do well in burrows with birds that they make through selective breeding. Wikipedia
