I've hit 100* on the egg surface!
Turned it down a notch......will wait and see if that will hold it there or if I'll have to turn it up due to the nighttime temps cooling the windowsill. Windowsill temps are 64 and will be cooling soon. I turned the warm side of the eggs to the bottom of the nest so they could warm on all sides, though I know that wouldn't happen in a real setting.
I'm wondering about something. When brooding on a nest out in the bush and the temps drop at night or even on a cool day, the bottom of those eggs are bound to cool off while the tops would be very warm next to mama. I wonder if the developing chicks migrate inside the shell to the warm side? An outside nest will always have a cooler side and I know a broody doesn't turn eggs that often, so how then does the egg itself stay a uniform temp throughout when one side is cool and one side hot?
Things to ponder.....
