Fill your 6 quart crockpot with water up to about 3/4inch under the rim. Add the bay leaves. Add the apple cider vinegar. Add the salt.
Use the broth to drink plain, add it to soups and stew or stir fries, or simmer it until it becomes thick for a gravy. Of course you can use it to make grains as well for other family members or if you are along enough in your journey to tolerate them.
This bone broth is fairly thick and may need to be watered down depending on tolerance.
