Kenji Lopez-Alt, author of The Food Lab, extensively tested this. It is not about the age of the egg (and I believe he tested hundreds of eggs). If you put the egg in the pot once the water has already reached a boil, it is easier to peel than if you put it in the pot from the beginning. Meaning, don’t slowly bring the eggs up to temperature along with the water. Since I read this it has worked for me every single time.
