How do consistent day temps well over 100 affect broody hatches?

Anyone know? Like many we are experiencing a major heat wave with temps regularly reaching 105 daily. We are on day 19.

I'm interested to know this too. I have a broody hen right now who is so far sitting on infertile eggs while I try to find her some hatching eggs, but I've been a little concerned about the heat as well. It is supposed to be 113 here today with no end in sight.
