I agree, make your own #DIY Eggshell Calcium Powder. Although I suggest boiling the shells, drying them in your oven at between 150 - 200 degrees Fahrenheit, grinding them up in a coffee grinder and or mortar and pestle then, buy some pharmacy grade "00" or "000" empty capsules and fill them up with your #calcium powder and it will go down painlessly. https://www.peteandgerrys.com/blog/diy-eggshell-calcium-powder
