Would the ground eggshells be in place of bone? You could certainly use them as a calcium supplement if you were to grind just the meat without adding bone. You'd have to calculate the correct amount to use to balance out the phosphorus. Ideally you want a ratio of about 1.2-1.4:1 of elemental calcium to phosphorus (eggshells contain about 39% elemental calcium). Here is a link to some info on calcium: http://www.abyssiniancats.info/calciumsupplements.php
And here is a link to a nutrient database to find out how much phosphorus is in the meat your feeding: http://www.nal.usda.gov/fnic/foodcomp/search/index.html
Remember to also subtract the small amount of calcium that is already in the meat.
