I had a very similar and successful experience. Take the egg out of the incubator, candle it (if there isn't anything developing just toss it), light a candle, 30 seconds later blow out the candle, pour a few drops of the hot wax directly over the crack, let it dry and return to incubator. I had one like this (on day 3 as well) and it hatched! He is named mr. Wax. A frizzled Naked Neck. It all depends on whether the membrane is broken through. If it is, it will probably die, if not it will most likely hatch!
