I just bought a bag of oyster shell to feed my hens. I've never had to feed it before, but lately my egg shells have been thin and some are just not formed correctly. I know I've got some older hens (I'll cull this spring, likely), but I'm thinking they need some more calcium.

I put out a small dish of it, but they don't seem to be eating it. Should I add it right in their feed? How much is enough? I'm probably over thinking this.

Put a dish, bowl or container of oyster shell within proximity of their food and they will find it and eat it as needed. Mixing it directly into the food will be wasteful.
If they need it, they will eat it. Keep it dry...when it becomes wet, it hardens and isn't as palatable.
