Question: What is an egg shell made out of !? What makes it so hard !?
Answers:
Mostly calcium, a little bit of magnesium and phosphorus, and trace amounts of proteins and other things!.
It's hard because of the calcium, which structurally makes up a good 98% of the eggshell, and the shape, round shapes are very good at distributing force around the structure!.Www@Enter-QA@Com

It's made of calcium, like bones!. Oyster shells are the same thing!. When you have egg-laying chickens it is always a good idea to feed them crushed oyster shell to replenish their calcium levels!.Www@Enter-QA@Com
