Put the ingredients in a crockpot and cover with filtered or spring water. Cook for 6-8 hours on LOW then remove chicken meat and save the meat. Put the bones back in the broth and crockpot on LOW for another 20-40 hours, stirring occasionally.
During the last hour of cooking, add a bunch or parsley (to pull additional minerals from the bones) and add other herbs if you like (ginger: 1 to 2 tsp graded for example).
Using a strainer, remove the bones and vegetables and pour into glass ball jars for easy storage. Can refrigerate up to a week or store in the freezer. (If you decide to freeze then make sure to leave enough space in jar for expansion, 1-2 inches).
Don't give the cooked bones to your pets! Cooked bones can splinter and cause problems.
When ready to reheat, DON'T use microwave, but reheat on stove top.
