I have a medium sized saucepan with a steamer insert, just perfect for eggs. I like my "hard" cooked eggs slightly runny in the middle still (not for deviled eggs obviously), so put the eggs in the basket over the boiling water for about 7 minutes. For harder eggs I'd up that to 10 or 11 minutes. I did an experiment once with one egg from the fridge and another from the nest box; they both peeled cleanly. It isn't 100% all the time though, so no promises about how they will turn out :-).
