The holes are tiny, I used a 1/16th drill bit. I can get out the duct tape and seal them, though.

I've got a small temp gun, but I can also pick up a thermometer/hygrometer combo at my local reptile shop.

Exterior temp is set to 103 right now with an internal temp of 88 with slight fluctuations. I was concerned last night at how low it dropped after having the incubator open and how slowly it climbed back up(hours), but I guess a little low is better than a little high? I'll try and leave the eggs alone now, lol. Thanks for the help!
