We had storm warnings but zero rain, no storms. It’s cloudy today! Supposed to be 100º or higher but maybe this will keep it cooler.

. I gave a broody hen some eggs on 12th. So this is day 5? I tried candling when she was off the nest, and not sure what I’m seeing. They all have some sort of development. One may have a blood ring. I’ve ordered a better candling light.
Can the weather be too hot for hatching eggs?
I am not worried if these eggs don’t hatch, but would have to decide what to do about mama hen.
