I just put eggs in my incubator today. The temperature was exactly right, 99.5, when I put the eggs in but then when I closed the lid, it was back down to 98.4 and didn't go up, even after waiting 30 minutes. So I had to adjust the knob again. I need tips on how to keep it stable even when I close it after I open it to turn the eggs. Same thing with the humidity. I opened it and went down from a perfect 50% to 45% and didn't go back up to 50%, even after waiting 30 minutes. Any tips are greatly appreciated.
