If using smoked turkey necks instead of wings, place them in a turkey baking bag and tie a knot to seal. Use a pair of scissors or a knife to poke small holes in the bag so the liquid of the slow cooker can exchange flavors with the smoked turkey neck. When done cooking, slowly lift and discard the bag or wait until it cools and remove the meat from the bones and return the meat to the pot. There's significantly less meat on the neckbone, so I often do not care to retain any of it. The flavor is all you really need.
