good call!! I noticed that instead of being too hot, now I'm too cool. I've hatched many times in my Brinsea Eco so far and not had these troubles. WHY now?? Anyway, I got it adjusted back and all is well, but I'll be keeping a close eye on it from now on. Sigh. ETA: BTW, my temp dipped down to about 98.8 for several hours, I'm guessing. I was gone most of the day. I got it back up and it's running steady at 99.4 right now. I'm leaving it. But.... what about the eggs?? Think they'll be okay or could I have done them in?
