What is the best way to boil eggs to paint them for Easter?

Boil the egg for about 10 minutes to hard boil a medium size hens egg, an extra minute or two will do no harm is all you are going to do is paint the egg. if you need to be sure it is hard boiled then all you need to do is spin the egg on a flat surface, if it is hard boiled it will spin on end, because the contents are solid, if it is only part cooked then it will wobble because part of the egg is still liquid.
