Is it poultry or specifically chicken? People that raise ducks or turkey also seem to raise their chickens better, IME.
I received a turkey from one of my suppliers that she said was only on her pasture for less than half the year, the rest of the time it was wild. I haven't tried it yet but I'm going to assume it'll be fairly decent.
I'll let you know how my wild dove, quail, and pheasant eating time goes too. Again, I'm going to assume delicious. I can't possibly conceive how a bird that is flying around running away from my hunt would have a virus, vs. a bird I just happen to stumble across which would still very unlikely have any virus/disease. Wild is best.
