okay, so i don't give my hens oyster shells, but i let them free range. theyre eggs are very strong, stronger than any ones at the grocery store. so does this mean theyre getting enough calcium? if not, will baked eggshells work just as well? is theyre anything else that calcium affects besides egg hardness? if i need to buy oyster shells, where can i get them?
