I told my mom to get some oyster shell when she went to Campbell's, but I'm not sure if what she got is really oyster shell. The bag only says "Coastal Shell" and only mentions "shells" and "calcium"- it doesn't ever say OYSTER shell. She got 50 pounds for about $10. Do you think it's really oyster shell or is it some other form of calcium or what? Thanks!
