110 is pretty high, but if it was not long enough to cook the embryos, then they should be fine. I read a study from OK that stated higher temps in the last couple of days actually makes the birds more tolerant of high heat exposure throughout their lives.The outlook for tomorrow’s hatch is not looking very good.
I’ve been checking temp and humidity every two hours today, and just noticed a huge temp spike, up to 110, maybe higher, I didn’t note the exact temp before trying to fix it.
Come to find out the lid some how shorted out, and was running at high and would not turn off. At all. So thankfully I found it now before I went to bed. I replaced the lid with another incubator top and am now hoping that this incident didn’t cook the chicks suppose to hatch in the next day or two.
I’ve seen some posts about young embryos being cooked at high temps, but didn’t see anyone experience spikes with 20 day old eggs to know if their chance of survival is low or not. (These eggs, first they nearly froze from the power outage, now they’ve been cooked!)
I've never tried it myself, but I have had heat spikes during incubation and am always amazed at how resilient these creatures are.
