Outside temps and Egg

[PeaFan]

I have seen info on low temps and eggs but what about high temps. At what temp (high temp) can eggs be and still be viable?
I am Mesa AZ and my hen has laid 8 eggs so far- she is not broody at all. This week our temp will be 117 high and like 90 overnight . Because of the high temp, are they no good? Will they start developing on their own? Should I discard them? Any advice is appreciated. Thanks

I know of other breeders in your area and they say that the hens keep the eggs cool. I would make sure the eggs are in a shady spot and hope the hen decides to set them.
