[Hound Dog Mom]

The shell of one large egg yields approximately 1 tsp. ground shell which should be around 2,000 mg. calcium. You want between 800 and 1,000 mg. supplemental calcium per 1 lb. boneless meat (really fatty meat may require a bit less and organ meat may require a bit more) to remain within the 1:1 – 2:1 calcium to phosphorus ratio. An egg without the shell has about 100 mg. phosphorus.
