yep, we've made this for years with legs and thighs. i cook 'em about 10-12 hours on low in the crocker with water and poultry seasoning and the leg tendons pull right out
you can get creative on your ingredients, too. i usually go with mayo, chopped pickles (sweet or dill), red bell pepper and onions, and some herbs, usually thyme and dill
forgot the chopped celery
