I followed the advice I saw on raising humidity by heating water before adding it to the bator so the temperature doesn't drop...and I got it way too hot. I don't know why I didn't think through that if the water is over 100 degrees it's going to raise the temp inside with no way to quickly escape. The water was steamy but not boiling (but still probably close to 200 degrees I bet!) My bator was 106 degrees this morning, and likely had been all night long. I've done that once before and had a temp spike. No movement in the last 4 eggs (nor was there last time) so I'm going to pull them this morning. I have another batch of eggs to put in. Hopefully it will go better this time.
