Stick a nail or needle into the larger hole and stir it around to break up the yolk and other membranes. Then use a small coffee straw to blow into the small hole, forcing the inside of the egg out of the larger hole. You can empty the egg into a bowl and use it for cooking later. Rinse the inside and outside with water and blow the water out of the shell. Once the egg is clean and empty it is ready to go into the dye. Be careful, the shells will be fragile at this point.
