I'm still in the "research phase". I've decided that I may as well build the cage first to make sure that I have separate, heated quarters far away from any of my current chickens that is completely inaccessible to any wild birds. I haven't decided yet whether it would be best to try and find adult birds or start with chicks but a lot of that might be determined by availability. The advantage of adult birds would be having fertile birds right away (apparently they take 4 years to reach maturity) and the advantage of starting with chicks is that you get birds that, while probably not exactly "tame" they hopefully at least do not panic when they are handled...which might be necessary if Artificial Insemination is the only way to keep them disease free. I'm not sure if freshly hatched chicks raised along side the Green Junglefowl would be "clean" enough or if merely hatching in an incubator that had hatched so many chicken eggs or any diseases that might be passed on through the egg might endanger the Junglefowl. I might be reading too much into things but there may be diseases carried by domestic chickens that they are totally immune to that might negatively affect the Junglefowl. On top of that, the idea of raising a small flock of poultry side by side for four years on a diet of mealworms, dubia roaches, nuts, berries, krill and seeds seems like a lot of wasted money. Besides, if I'm going to go to all that effort I may as well try to raise some pure Green Junglefowl. I did contact one seller that did not want to sell to someone who would be attempting to create hybrids. I wouldn't want to do that with Red Junglefowl but I don't see any chance that there would ever be the same problem with creating a bird that looked like almost pure Green Junglefowl but that was not pure. It seems that there are actually already quite a few Indonesian breeds that were derived using Bekisars but they have been bread for a lot of reasons other than trying to get them to look like Green Junglefowl. Instead it seems that most of the focus has been on their crow. Anyhow, it looks like creating a bunch of Bekisars (but with domestic chickens, not Red Junglefowl) shouldn't be all that difficult. Crossing those back to pure domestics should be fairly easy. Getting fertile females seems to be the hard part. If it doesn't happen in that generation then you have to keep at it over successive generations with lower percent Junglefowl males until you get fertile females. Hopefully a Bekisar doesn't take 4 years to reach sexual maturity. Then who knows how many generations of inbreeding and line breeding to see some Green Junglefowl traits (especially that comb). Honestly my biggest concern is my wife...let's say "not supporting" my efforts. I already don't have time to focus on building a proper enclosure because she has me building a barn this summer and various other projects.
