Thanks for talking me down ha! So far so good. The temperature has been between 98 and 102, with a slight dip this morning between 330 and 630 from 100 to 96. Definitely not too concerned. After a few hours all 3 thermometers synced up pretty well, so since it's a still air incubator, i put one in front of the eggs, one on top of them and one behind. The front stays around 101-2, the back stays 98-99. I'm amazed and sort of impressed! It's a really basic contraption!
I adjust the temps by either moving the heating lamp itself over, which creates a slightly larger air vent, or by moving the whole top at once to keep the same amount of air going in but bring the light closer to the eggs. It takes maybe a centimeter or half of one to adjust by a degree. This is probably one of the neater experiments i've attempted
