Homemade Chicken Broth

I took some older hens to freezer heaven about a month ago. My awesome wife has been putting them in the crock pot over night, and cooking them down to make broth for the freezer. When I get up in the morning the house smells so awesome. Then when she makes soup, oh it is so good. All the left over scraps, bones and miscellaneous inedible pieces go back to the chickens, and they just love it as much as I love the soup. I never seen them eat something so fast.
