Mine aren't due until New Years, but always hatch a day early, and recent hatches have started 2 days early, so I expect someone tonight or tomorrow morning. IDK..I have 4 different thermometers, and I don't think I run it hot, but maybe all 4 are wrong and I do. No, I've never calibrated.![]()
I don't calibrate either. I can feel through the holes, how humid it feels coming up through there. I know, sounds wrong. When I am turning eggs, I just go by how they feel and watch what the thermometer is saying, then go from there. I know how I like them to feel for incubation.
No one try this at home until you have incubated for a few years..lol...
