The wild type color pattern isn't that uncommon. Gold Duckwing. He looks like a game to me.
Real Red Jungle Fowl are purported to be a bit hard to raise: fragile, disease prone, nervous.
American games are just the opposite... As long as you are only keeping one rooster or can separate them.
check around some of the other threads, look at the roosters in the pictures.
Welsummer roosters are similarly colored, (except for their yellow legs)
but as I said the color pattern is not uncommon
