i had 42 eggs in a GQF hovabator with turner and fan.  i have removed 4 and broke 1, so we have 37 left.  i didn't know you were not supposed to put one by the egg turner motor, but it is candling fine and moved now to another spot vacated by a quitter.  can't see into several of the blue EE/AA crosses, but no smell or weeping so i am leaving them alone.
i have 20 black javas, two GLWXjavas, 3 brown leghornXjavas, 4 EEXJavas, and 8 EExAAs left.
i have three thermometers in there, and they are vexing me.  one is a mercury liquid thermometer (meant for measuring temp of beer during brewing, and more expensive than the others).  i have been putting more faith in it.
the other two are the flat plastic freebie GQF sent with the bator, and a digital hygrometer/thermometer combo from 
wal-mart (acu-rite).  the GQF freebie runs 2 degrees off (lower) than both my home thermostat AND the brewing thermometer.  the hygrometer combo just stops at 95 degrees no matter what. 
  it's also off by 4% on humidity gauged by calibration, so i have a suspicion that is at least 4 degrees off (low) on temp.
given this situation, what would you do?  which would you trust?
