Sorry you are having trouble now. 103 is high, and hot is worse than cooler. Mine seems to fluctuate up and down so much, I figured I couldn't get as technical as you are getting, haven't even checked for hotter spots. I'm just trying not to get too hot, and if some are cooler and take a little longer to hatch, so be it.
I'm amazed that I now have 2 little duckies, and my turkey hatched! I'm really shocked that the turkey made it. They are finally resting and have fluffed up nicely, but I have 2 more pips working, so I'm not taking them out yet. Hopefully these others come out tomorrow.
Oh, and I sympathize with the exhaustion too.... I haven't slept more than a few hours at a time either, for the last couple of nights.
Best of luck!
