So I set up the incubator for my hatching eggs, watched it for a day and temps were great. Put the eggs inside, and then noticed the temps were a little high yesterday afternoon. So I twisted the dial (hovabotor basic- no fans, no thermostat- I think it's on a rheostat) to turn it down just a bit. Later I looked at it when it was time for my evening egg turn: it was 120 degrees! I must have twisted it the wrong way.. I turned it down right away, opened it to cool it off and walked away worried. This morning: 89 degrees. Jeez I'm having trouble. Are the eggs likely done? It could have been about 4 hours at the high temp, overnight at the low. I went to the coop later and it looks like I have a hen who's feeling broody. Is it possibly that they could be transfered to her since my incubator is proving problematic? Or should I just get the temp set and keep trucking? I cracked open one egg, the yolk had a VERY pronounced white disk, bigger than I've seen on regular fertile eggs like we eat. Mixed feelings on this, what would you do?
