Did the heat do this?(Hatching eggs)

Photos will be posted in a few minutes!

We had a 100+ heat wave Saturday-Today. Our 3 broody chickens have been trying to stay on the eggs despite how many times we've kicked them out to cool off and hydrate.
I just candled the eggs and they're still thriving.
Cayuga/Khaki Campbell mix.
Incubation started Thursday at 2pm.
We got 11 eggs total.

Once the photos are posted below, can anyone tell me if the heat bumped up the incubation or if what I'm seeing is normal for today?

Correction! 9 eggs, not 11.
Tried my best with getting the photos. Hens were upset with me

While I am unfamiliar with those breeds, those look pretty normal to me. What are you seeing that is concerning to you?

What day do these look like?

About day 5?

Looks normal to me. I don't have any research to back this up, but in the heat I wonder if the nest is insulating in the opposite sense and actually keeps the eggs cooler. Would be something interesting to experiment with.

Then they look normal.
I was concerned because with how hot it was, the hens could stay off the nest for about 2 hours and the eggs would still feel hot.

I just got the hens off the eggs again to go cool off and drink water. I found out that I miscounted when candling the eggs last night, I assumed it was only 9 eggs but there are 10 eggs in total. I'm going to candling them tonight one more time just to make sure it isn't one of our own duck eggs.
