egg shells.

I read somewhere that the shells can be dried in the microwave and then ground up in a coffee grinder. Just my 2 cents worth

Sure they can!

Of course, the chickens couldn't care less if the egg shells are ground or unground, microwaved or unmicrowaved.

I just air dry to make crushing easier, then toss out. Grandma didn't even bother with that. She'd just toss them out with the other scraps to them.

I just put mine on a pan and put in the oven after I'm done baking something else in the oven and have already turned the oven off. Dry shells, no wasted energy.
