I've actually gone with a setup where I used multiple thermometers. One is attached to a thermostat that I use to power my ballast heat source. The 100w reptile lamp is trimmed out so that the incubator runs 99.5*, and is adjustable for swings in ambient temp. I then use two 17w seedling mats to bring in extra heat should the incubator get cold. I initially started with one mat, but found that if the ambient temp dropped 10 degrees, it could not keep up on it's own. So I installed the second, and now find that the temps never drop below 99*. Once the temp reaches 99*, the heat pads turn on, and turn off once the temp reaches 101*.

. It pipped the wrong end, but seemed to be doing fine, lots of noise, and was zipping, so I figured I'd be ok to go to bed, got up this morning and it had only zipped about 2/3, but no noise, no movement, took it out of the bator to check and it was dead. Really malpositioned, both feet behind head, wings kinda to the front, like the legs pushed them forward. Wish I had stayed up now, poor little guy. The yolk wasn't absorbed all the way either, but the blood vessels had receded fully. Still 2 eggs to go, it's officially day 21 here! 3 little babies have already been moved to the brooder!
