First, don't use fresh eggs from chickens in your yard, use only store bought eggs (they are marked "fresh" even if they are 3 months old).
Second, there are lots of "tricks" to get the eggs to cool and shrink away from the shell, but if you've been making eggs for years, I assume you know those.
Lastly, I use a teaspoon to scoot under the shell, and around the egg to get the shell off nicely.
