I am an amateur at this so listen to others first.
You can also listen too. I put mine on lock down last night at 8pm and raised the humidity. 18 days to the hour. Temp stayed 99.1 - 100.3 I would guess the whole time. Just an hour ago, less than 19 days into a 21 day hatch, I heard chirps. I do not see but one egg externally pipped but I hear 3 or more different chirps.
