I am at day 12 and I woke up this morning to a bad temperature spike--112-- (Nooooooooo!) in the Bator. Its a Hova Bator 1588. I re-toggled the temperature rocker switch and am waiting to see if that works. Question: all the switches were down, except 6--which was up. Is that the proper factory setting? I had it running for 2 weeks before I added the eggs and the temperature was holding very even at between 99.5 and 100. Also--why does this happen? it seems to happen to others with some frequency. I guess all I can do is wait and candle and see if I have any survivors. Major bummer!
