newly set eggs and sudden temp spike

[FromChictoChick]

I had the incubator running for over a week with temp and humidity spot on.

I set the eggs out all day then I added them to the incubator

The temp suddenly spiked to 103! I'm adjusting back to correct temp and lifted lid to release some heat

Why did this happen and did I likely spoil the whole batch? ??

What kind of incubator is it? Sometimes that happens with the Styrofoam incubators. And don't worry about having killed them all! I had some who survived a temp spike of 113 degrees...twice! So I would say just candle them and see how they're doing in there.

I just put them in, would candling the same day show anything?

OH! I misread your post - I thought you had had them in for a week already. The temp spike makes sense then - that happens a lot when you put eggs in, not sure why but someone else could probably tell you what causes it. No, day one would be too early, but by day three you can usually start to make something out, so you could try then.

How long were they at that temp? If it wasn't too long, I think they will be fine. I would candle them on day 7. You should see veining if everything is OK. I have had temps drop low when I added the eggs but not go high. Good luck.
