Game Fowl School !!!!

Not trying to hijack thread but I got a few questions . I got me some Phoenix Fowl chicks this past spring. I was told phoenix were made by crossing game fowl to japanese ornamental fowl. I'm not interested in fighting them. All I'm after is some fowl that can survive on some wooded property. I started with 7 cocks and 5 hens and have not lost any yet. The Phoenix will tolerate other cocks as long as they were all raised up from chicks together. They also tolerate young cocks born in the flock. Now they spar their butts off but so far so good. Do you think I could mix in some pure game blood or would that mess up the whole make up of what I got going?
