Temp. jumped to 107!

This is my first time incubating, using a DIY incubator. My eggs are at 13 days and doing well up to this point. I came back home and found the temp had gone up to 107! No telling for how long, but it's possible it was up to 3 hours.
Have I harmed them?? I've read a million places that 103 is enough to damage them.

It really depends on how long it was like that. If you caught it really quickly, then they'd be fine. However, if it was long enough that the internal temperatures of the eggs warmed up to 104 degrees or more, then they will have died.

All you can really do is wait a day or two, candle, and see if they are still alive or not.

Thanks for the reply. It's stays pretty cold in our house, so the temp rises pretty slow when I need to bump it up. It was 99 when I left, so fingers crossed it wasn't long. If it did harm them, will it show a blood ring in just a few days? Or is there another way to know? Some eggs are marans and my only viewing to know their development is the growing air cell.

I've had temps spiked up to 104-105 and turned out fine, though it was only for a short amount of time. Let us know how it goes, be interesting to find out if embryos survived at that temperature spike.

UPDATE* We've had 7 successful hatches, all healthy so far. They're 3 days old today. There are 4 that haven't pipped at all. Today is day 25 and I'll be doing a float test. Candling isn't showing much with them being marans.
4 hatches were on their own, 3 were assisted the next day. They were getting shrink wrapped. I'm assuming this is due to humidity levels becoming wonky. I was having a hard time lowering humidity after the other hatches and we're in a naturally humid area(also having thunderstorms that day). They came out fine on their own after finishing their zip for them and peeling back the outer membrane. On the first day of hatching we did wake up to find we had lost one chick that had started to zip around 2am. This is how I figured out the later hatches were becoming shrink wrapped.
