Do you use the egg shells as calcium for the hens?

I don't microwave them. Microwaves mean radiation, and radiation is unhealthful. I let the egg shells dry naturally in a bowl reserved for drying eggshells. Then I crush them and mix them into the chickens' feed.
I was wondering today, is it okay to give crushed-up duck egg shells to chickens? As in, is it safe? Duck egg shells are harder to break than chicken egg shells, so if I feed that to them, will it make their eggs that they lay have stronger shells? I was planning on doing an experiment once they are out of the "first few eggs are unusual" stage, but if you can advise me, please do.

Hello and it’s great to have you here.

A bit like Blooie, I make scrambled eggs with mine occasionally, shell included, and feed back to the girls.

Yes I do. I used a little cattle think I found at tsc that had 2 separate sections. I put grit I. One and crushed oyster shells in the other so they always had it there if they needed it!!
