Hello! I’ve had my incubator running for a few days, and my eggs arrived today! 
I’m letting them sit for 24 hours before putting them in the incubator, so I still have time to make adjustments! My question is this:
I have a Brinsea mini II advance, and I’ve been monitoring the temperatures and humidity with two Govee thermo-hygrometers in the front and back of the incubator, laying flat. The one in the back always reads cooler!
I did swap them to test that one wasn’t faulty, but got the same results.
Is this normal? Would it be better for me to have the temps a little higher so the ones in the back stay a little warmer? Or will they be alright? Should I try putting a foam insulation panel on the wall they’re against?
