To make chicken broth, once the chicken is cooked, pull the meat off the bones. Store the meat in the fridge until ready to use. Put the bones back into the crock pot. Add two more whole carrots, 2 whole stalks celery, half an onion, and another bay leaf. Add 5 more cups of water, turn the pot to low and cook an additional 4 hours. Strain the broth through a fine mesh sieve. Refrigerate or freeze until ready to use.
