Just threw in my second clutch of call duck eggs into a new Oct 20. I have a water wiggler in there with a Brinsea spot thermometer inserted into it and a radio shack thermometer. The radio shack and brinsea (inserted into wriggler) thermometer both read 37.5, but the built in alcohol thermometer that is placed directly under the fan reads like 102F Which one do I go buy? I am being super paranoid after the first clutch eggs went full term, failed to hatch, and were deformed with twisted beaks and odd shaped heads. This was in an R-COM mini, threw the sucker out and bought the Oct 20 Eco. Eggs have been in the bator for three days so far.
