If the health quality of the bird is important to you, find a local farm, farmstand, or wholefoods-type market where you can get a farm bird raised on quality feed and in a healthier environment. Most (not all) supermarket birds are factory-raised, wing-to-wing, in wretched pens. A farm bird will cost more, and that's a show-stopper for a lot of folks, but if you have the means or interest, the option is available.
