The thermostat probe is place in the middle tub, and I have a thermometer in the top middle tub as well as the bottom middle tub the variance is less than 2 degrees from top to bottom.

I do have a fan on the top circulating the air.
The temps IN the tubs vary from 88 at the bottom to 90 at the top.

You need to place both T-stat prob and thermometer prob in the egg box preferably taking the temp in more than one egg box.
