Did you drop it. I droped one of mine and it had a sad ending. It lived about three days. I read on here one time about someone putting tape on a hole. I really din't know sounds like a good idea to me about the candle wax. But i might be wrong Sorry i can't help
how long has the egg been in the bator/ how long has the hole been there, if its not in the bator yet i would just toss it, but thats my opinion, now if it has been incubated and theres development i would wax it asap and get it back in there,
