I didn't read every single post, but I don't think anyone mentioned the fact that if GMO chickens eventually replace our egg and broiler chickens, the GMO technology is something you "license". As such, it may no longer be possible for you to try to develop new breeds with your GMO chickens without violating the license agreement (just like copying a computer program). Granted, very few of us do anything like that, but a handful of people on this board have done so. While I have no plans to breed chickens, it's at least comforting to know that the option is still available to me.
