All considered you got to wonder how the chickens managed to hatch eggs LOL

What you do is test/calibrate other thermometers and hygrometers, note their accuracy differences and compare them to the incubators readings.
This is how I do it....it made my hatches much more successful, especially in a friends incubator which I discovered was off by 6-8°F:

Get some local eggs, shipped eggs are heartbreaking.

Like I said will get chicks and then hatch my own eggs
