Most of the factory farm animals we consume would die in the wild. There is a slim possibility that a small fraction could regain some type of feral survivability but highly unlikely. We have breeded them to be sustained by us. However there is one case to examine. When a tropical storm hi Hawaii many years ago it destroyed many chicken coups in a native village that was abandoned and rebuilt further away from the original location. The people never recovered their scattered chickens and they did not have any natural predators so they became wild and flourished. When developers moved in and began building beautiful resort bungalows on the original village site everything seemed to be going well until the fat tourist got sick of being woken up at dawn every morning by the wild chickens. Do a google search for chicken problems in Hawaii for more info.
