I have a mixed flock, so tend to use a low calcium feed. And give them oyster shell on the side.
I also have a bit of experience in water treatment, and one of the things we use to neutralizer water is "Fine calcite"

Now the fine calcite in those bags is 95% CaCO3. And at a very similar mesh to the oyster shell I give my hens. It's also significantly less expensive pound for pound. Is there a reason I couldn't give my hens the fine calcite instead of traditional oyster shell?
