Grinding Eggshells for Homemade Pet Food

• Collect eggshells as you use eggs
• Wash the eggshells under cold water
• Let the eggshells dry off on the stove-top or in the sun.
  

Once the egg shells are dry, bake them at 300° F. This helps to make the egg shells even more dry and brittle for easier grinding. In addition, this helps to get rid of the mineral oils that have been applied to the egg shells to keep them from drying out in the store.

Add egg shells to a blender, grinder, etc. and grind. Keep grinding until there are no sharp pieces. The egg shells should become a powder although it most likely will not be a fine powder. Use a sifter or strainer to remove large and sharp pieces of egg shells.
