What ionic compound, is the primary source of a chicken's egg?

I think it is calcium carbonate? If it is thought what is the logical/ explanation behind it can someone please explain this to me.

Btw what would be the chemical equations for an egg being placed in water, and for an egg being placed in vinegar?

Would the vinegar one be: calcium carbonate + acetic acid = water+ carbon dioxide gas + calcium acetate?

There is a big difference between an egg and an egg shell.

Calcium carbonate is indeed the primary constituent of an egg SHELL.

CaCO3 + 2 HCOOH = CO2 + H2O + Ca(COOH)2
