Oh...so the rest of that is that it might actually be EASIER to cross a Green Junglefowl with a domestic chicken than with a Red Junglefowl (although not as easily as crossing domestic with Red Junglefowl). The resulting cross might be MORE likely to be fertile since there is more genetic commonality (Red and Green Junglefowl have lived side-by-side in the wild with few if any natural hybrids). I'm rather encouraged by this but I can expect the early crosses to be less fertile and short lived but hopefully there will still be some fertility with F1 males and if those are crosses with domestic hens and then those are crossed to each other hopefully fertility will be decent and hopefully some of those Green Junglefowl colors will also show up.
