>Should we just release them back to nature and possibly let them die out there? IMHO, not my field. Most of the wild animals that live a time in captivity needs to learn again with human help where obtain again food before to completely return to the wild. If domesticated species were going to be released, by extrapolation I deduce the matter would be to know to what extent did they lost their instincts (due human selection), and how they could be guided along N generations to recover it (this plant smell is poisonous), or if the above is to much to learn at least were to find the food, for what an habitat would be needed first, in companion of a high number of animals for to keep a high genetic diversity, with migration paths (climate, group mixing, etc).
