Obvious point on the animal welfare front, some animals are safer bets simply because they don't lend themselves to intensive farming. Sheep are a good example although not without welfare issues.
If you know some countryside-type folks you may well be able to get hold of pheasant and/or rabbit reasonably cheaply. Again, not without welfare concerns (for pheasant) and you have to be ok with people shooting them, but you're guaranteed to get something that's been living (semi-) wild for most of its life.
