Son of a bleep. I've got a HovaBator 1602n running right now - the model with the wafer thermostat. I've got 22 eggs in there, we're late day 20. Five are pipped, one chick almost out, and we heard a huge *PING*.....temp has dropped to 96*. I'm hovering over it, adjusting it non-stop, trying to get the heat back up without getting it too hot, but I'm about 90% sure the wafer blew. Piece of doo, we just replaced the wafer in it 6 weeks ago, no way I thought it was about to go, and I don't have a backup. My other bator is set up at my daughters school with eggs right now, so I don't have that available. What do I do? We've got every possible heating thing going in the house, trying to establish SOMETHING that will give a good temp. Right now we're trying a heating pad with a rubbermaid tub over it, but I don't think we're going to get to the right temp. I'm seriously considering sticking them all in my shirt - totally freaking out. Help me save this hatch - I'm open to ANY suggestions you might have.
