I guess I'm in the minority on this thread. I do offer oyster shell to my flock. They lay a lot of eggs. They eat more than just layer feed. They eat a lot of foods that are not good sources of calcium. They find a few that do have some calcium. We have a shorter season than many for both green feed and bugs. We don't have calcium rich sand here. I don't go through a lot of oyster shell, but it's there if they need it.
People that are not getting enough calcium steal it from their bones, to keep functioning. Calcium is involved in a lot of important processes in the body. I don't cull my chickens when they're 2 years old, so any imbalance in their diet could get worse over time. I've always thought oyster shell was cheap insurance. That's why I offer it.
