Wash chicken bones and place them in a crockpot. Add enough water to cover the bones and fill ¾ths of the crockpot.
Tear the leaves off the rosemary stalks and add to the crockpot.
Simmer on low for 2 days. Once the crockpot cools, place it in the refrigerator until the fat solidifies and rises to the top. Skim off the fat with a ladle or pour the broth through a strainer to strain the fat. Discard the fat and you have bone broth!
