This is what I do, and it has worked well. I add a teaspoon of baking soda to the water, bring it to a boil, add room temp eggs, cover and simmer on low heat for 18 minutes. I then take the pan and put in the sink and start running cold water in the pan. Once the water in the pan is very cold, I add ice cubes to the pan. I wait about 5 minutes for the egg to have cooled complety, and then I tap the fat end (air pocket) and peel from that end. Seems to work well. I have done this on same-day-laid eggs without issues.
