Do not trust the digital ones. I bought a digital thermo/hygrometer and put both the mercury one and the digital one in my bator when I started this hatch. The digital ALWAYS read about 5 degrees hotter, so I turned the temp down, thinking I was running too hot. Well, when I pulled eggs out for the first three or so days to turn them, they always felt "cold" to me. Digital was reading about 101 and the mercury was at about 96 or less sometimes.OH NOOOOOO!!!
I think I may have been either WAY hot, or WAY cool in my bator for a few days.
I have three thermometers, I took the two with hygrometers out of the incubator to check the temps and humidity of my new hatcher while building it and left the third. No adjustments, holding steady temps.
I added my Delawares and Barred Rocks last night and put all three thermometers back into the incubator. Well, my digital one is reading 105 degrees, my hygrometer/thermometer (reptile thermometer) is reading 99.5 and my little plastic one that came with the LG is reading somewhere between 98 and 100 (that one is really difficult to read through that little window). I had been making the adjustments based on the digital one!! They had all been reading the same thing before I moved them around. And they have been there all night, so I know they have had plenty of time to adjust.
I'm buying some new aquarium thermometers today. I just hope I didn't ruin my whole hatch. I have been losing so many eggs and I had thinking it was because they were shipped.

Hatching is tough.
Now, I hatched 7 of 11 Serama babies the last hatch with just the mercury thermometer (two died at pip.... just never hatched)...so I know that there is something wrong with this digital one. I took it out. I half blame keeping the eggs way too cool the first few days on part of the reason for my low rate of viability this time around. I bet your temp is right on with what the mercury ones are reading.
Edited to say that I am using a still air incubator, so I keep mine between 101-102 ^..^
