Hello, I purchased an R-com 20 and put 16 eggs in it and hatched our only 4. Now my question is during this incubation every other day the temperature would fluctuate. It's set at 37.5C and during the night would drop down to 36C. This happens often with this machine. Morning will come and its back to 37.5C. It is no where near a window. It will either be 37.5C or lower. It won"t go any higher. During lockdown it wouldn't go higher than 38C. The humidity was always correct though during development and lockdown. What am I doing wrong? I have re calibrated the temperature and it's still fluctuating. But here is the stupid question. If I am to call the R-Com people for assistance, how do I dial their phone number? I have never called outside the US before.
