Great bulk buy
Consistent product, better value to buy in bulk. My hens produce eggs with hard shells.

Oyster shell for ducks
Works great to make our duck egg shells strong. We put it in a dish near their water and they seem to to know when and how much they need. We also used it in our garden with Tomatoes and Zucchini for added calcium to prevent bloom rot.
