Why are my egg shells sticking to my hard-boiled eggs?

Add eggs after the water boils.
The problem with starting your eggs out in cold water is that the gradual change in temperature causes the egg's proteins to stick to the membrane of the shell more than when dropped in hot water.What does it mean when the shell sticks to a hard boiled egg?
A fresh egg tends to stick to the shell when boiled due to its high acid content. As the egg ages, carbon dioxide and moisture inside the egg gradually leak out through the thousands of tiny pores in the shell. This lowers the acidity inside the egg and makes it less likely to stick to the shell when boiled.Why won't my hard boiled eggs peel easily?
The fresher the eggs, the harder they are to peel. This is because the egg white or “albumen” in a fresh egg has a relatively low pH level, making it acidic. When cooked, these fresh egg whites bond strongly to the inner shell's membrane.How do you get eggs to peel easy?
Adding cold eggs to boiling water (rather than starting them in room-temp or cold water) helps the eggs release cleanly and more easily from the shell.Does vinegar make eggs easier to peel?
Add salt and vinegar to the water before cooking.The salt permeates the shell a little bit, and the vinegar helps to break down the shells, making them easier to peel.
