I just read a post that said do not change it, even if the temp fluctuates (I think that is how I translated it). I've had my incubator (brower top hatch) running now for 2 days without eggs. It's been sitting at about 99-100 degrees. This morning, I got up and it read 102~! I adjusted the temp down. When I have eggs, should I be just leaving it alone or watching & adjusting? Sorry, newbie questions... I want this to happen (hatch). I am going to be such a nervous nellie!
