WHAT ABOUT ASIAN CLAM SHELLS FOR CALCIUM? ANYBODY KNOW?

[kcfuerst]

I am wondering if the shells of invasive Asian Clams as they are removed from our waterways is a good source of calcium for chickens. How does it compare to oyster shells? Anyone have any idea??

Thanks!

My guess is that all bivalve shells are calcium based, so should work as a source if you have a source and way to crush them.

Thanks. Had a feeling it was OK but wanted to check.
