I was worried because my main thermometer 's batteries died last night...It runs on a 9 volt and so I had to wait until this morning to get a new one....
I just candled...All 20 of my eggs have movement!!! I am so excited!!!
That's one of the reasons why I use a plan old lab thermometer. I used digital for awhile and then went back to plan and simple with both my thermometer and hygrometer. I always wondered if the moisture inside the bator especially at lockdown would make the internal parts of the digitals corrode or short out.
