... could feeding them egg shell contribute to them eating their eggs?
The consensus around here seems to be that, yeah, it might
. Sounds like you are doing it but baked egg shells should be ground up - use the palms of your hands (or, some use wax paper and a roller). If the chickens don't recognize them as egg shells, the idea is that they won't try sampling their own eggs.
I've gotta say that relying on eggshells, unless the hens have a 3%+ calcium feed ration, doesn't make a lot of sense to me. And, if we add low-calcium treats to their diets (including scratch), we are reducing that 3% calcium . . .
Finally, chicken manure is a very high calcium fertilizer. What that tells me is that the hens are losing a lot of calcium that is in their feed.
You can't put ALL the calcium back into the hen by recycling their eggshells. Don't rely on eggshells alone. Make sure your feed has adequate calcium or give 'em oyster shells.
