This is super simple. After you have eaten your first meal and picked the bones clean for all those future meals, save everything else - bones, cartilage, skin, everything. All this can be frozen to combine with future chickens or you can make right away. Anyway - save all that and put it in a crock pot, Add what ever veggies or veggie scraps you have - carrots, celery, onion etc. Add a bay leave. Fill crock and its ingredients with water - cook for 10 hours on low. Pour off the broth and store in fridge for up to 5 days (or can), discard the bones and veggies. Use this broth for a whole assortment of cooking in the week ahead.
