Sometimes the dragon accidentally puts a minor scratch/pinhole in the egg with her claws as she maneuvers them or when she covering them. Then a little bit will leak out ....that's probably what happened. If they smell get them out right away, they are not alive now. If you're in doubt you can just toss them in a small plastic bag with a bit of water, they can not survive being wet so there's no need to freeze them at all.
