We just got our first hova bator genesis and we aren't sure what is going on with the temps. The digital readout says its pre-set to 100.0 and its been fluctuating between 99.3 and 99.7 which seems fine. But.... We also have 3 digital thermometers in there at egg level. 1 is reading 97, another is reading 97.5 and the third is reading 98.4. The digital readout and all 3 of the egg level thermometers have been pretty consistent for 2 days now. Should we trust the incubator readout and ignore the other 3 thermometers or is something wrong with it and we should send it back?
