Extreme heat and eggs..will they hatch?

[Peanut59]

My OE hen decided to start sitting on her 9 eggs on July 3. We have had record breaking temperatures of 102-109 in the past couple of weeks. Are the eggs in her nest any good? Is she wasting her time? If so what should I do?

I'm sure they are fine. Mother nature is strong.
