I feed eggs shells to mine instead of oyster shell. They are free range. I don't know if that makes a difference.
I have never had a problem with their shell thickness. I started feeding them oyster shell because I kept getting told I should. My grandma gave me some of her oyster shell to try and I never noticed a difference in their shells. I still have some in the mudroom that I have fed them yet. XD I just feed them their own eggshells back to them when I have them. I don't bake or crush them, just rinse and throw them out with the other scraps they get. I haven't had a problem with egg eating, but if I ever do I'll just start crushing them.
I would not recommend feeding them store bought eggshells unless you are going to bake them. Store bought eggs can carry salmonella.
