Last night I put a new batch of eggs in my Brinsea incubator including some expensive eggs I had shipped. Overnight the temp spiked to 104f which had never happened before. I have no idea how long it was at that temp but it could have been as long as 7 hours. I have reset the incubator and have a digital thermometer in there now too to monitor the temp. My worry is that all the eggs may now be “cooked” including my expensive eggs. Can eggs survive a spike in temp like that on day 1? Thanks for any advice.
