If you have spare bones from your dinner lying around, grinding them up is a great way to find a use for them. A good meat grinder or blender will turn soft bones, like those from chickens and other small animals, into powder. Ground bones are great as a source of calcium in raw and dog food or as an organic fertilizer for plants.
