[QUOTE="Florida Bullfrog, post: 25958251, member: 540891"] In my case, nature is the primary selector. Either my free range birds live or they don’t. I have come in behind natural selection and then selected for traits I’ve wanted. Sometimes with no ill effect and other times with major negative effect. I’ve culled many otherwise healthy and rugged roosters because they looked more like the gamefowl side of their ancestry and not the junglefowl side. What I found in generation 4 is that many of my birds were coming out with strong JF traits, including pullets having low pulsing tails when they’d walk and little to no combs. But was I also found is that the gen4s couldn’t handle common sickness, much as pure RJF cannot. The more I selected for superficial RJF traits through tight inbreeding the more I also brought to the surface very tangible traits that were not beneficial to my goal, either due to inbreeding depression or to actually activating negative RJF genes . I believe that by infusing American gamefowl in that has a strong JF look I can freshen up their genes and still select for a RJF appearance, albeit larger than my original hybrids. But I’m learning more that I’m better off keeping selecting for superficial traits at a minimum. [/QUOTE]
