What kind of bator? At this point, I would probably put them in the oven, with a big pan of hot water on the lowest rack. On the very lowest 'warm' setting, just barely turned on. Oven light on. Once the oven warmed up a bit, it could be turned off, and just the oven light used for a heat seat source. It would have to be very carefully monitored, of course. Another option would be to throw a string of non-led christmas lights in the bator. They are waterproof, so the humidity wouldn't be an issue for them. And they put out some heat, but not too much so that the hatchlings wouldn't be hurt coming into contact with them.
I feel your pain. I have $150 dollars of hatching eggs waiting, and managed to blow up BOTH of my Genesis 1588's. I am scrambling for a replacement today!
