Does anyone have information about the quality of oyster shells as an
extra source of calcium for laying hens? One concern I have is that
oysters are bottom feeders and wonder what other "ingredients" might be
contained in the shell. Possibly the oysters are farm raised now?
Other sources of calcium that could be offered free choice? Thanks for
your help.
