Over the many years that we kept chickens, people told us we could cook their egg shells in the oven for 30 minutes at 350, then crush them and feed them back. It reduced the amount of oyster shell we had to feed them and made their egg shells stronger.
Now we have parakeets and they do consume the chicken eggshells. The eggs they are laying have stronger shells; so much the better for hatching strong chicks. We have not had to supplement with cuttlebone since starting this practice.
When we get too many, I put the shells in the blender to powder them, and sprinkle it over the flower beds that have tulips and daffodils and other bulbs. The flowers are improved, and I can keep even tulips for 15-20 years instead of having them peter out.
