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!
 
I have Coastal Brand Poultry Shell, if that is the same kind you got. It has ground oyster shell in fine print on the back.

As long as it is calcium carbonate and safe for animal consumption, it does not matter the source. Even if it doesn't say, it's probably still OS.
