Well duluthralphie, the only thing I can think of is to throw out what its telling you the humidity is... Mine was telling me it was running 10% in the incubator but the air cells were telling me something different, I no longer use one at all for incubation, I do put it in at Lockdown and if it says 65-68 I know I am good (it is more than likely wrong, but that's when I get my best hatch rates so I go with it)
Also, I know the digital little giants I bought weren't keeping accurate temps, I took mine back. My sis lives in Oklahoma and she cant seem to get about a 60% hatch rate using the little giant.. I try and walk her thru different fixes and it had gone up a bit ( from about 40%) but still nowhere that she feels good about.. Its frustrating to be so vigilant and on the ball only to have them die in the shell the last couple days..
I am by no means an expert and there are so many more on here that are way more experienced and will tell you to disregard what I have said, but for me it works.

Was in a corner of the pen, no obvious signs of trauma... Oh man I hope this isn't the beginning of losses! Last year I lost the majority before 2-3 weeks... This one was around 8-10 weeks old.
