Whenever you open your incubator it will try to compensate by turning the heat on full. Then it spikes and it turns off the heat. Eventually it gets back to an even keel. During all this see-sawing, the temp inside the eggs (where it matters) stays relatively stable. You can get remote thermometers where the probe is inside a fake egg designed to simulate a real egg. Unfortunately they can't be calibrated (or mine can't, at any rate). Nevertheless, they do show how much more stable temp can be on the inside of the egg.
I've seen advice to leave the incubator alone for an hour after opening it. I rotate my eggs to different spots in the incubator every day and get those wild swings. It's no more harmful than mama hen getting up for food, water & broody-poo.
Your humidity will be just fine. It will most likely go up when the babies begin to hatch. They're pretty soggy from being encased in egg stuff. Best of luck!
I would have left it alone, but it was already up to 103 and the temp on the incubator had already stopped and regulated. I watched it for a good 10 minutes to see if it would go back down, but just kept going up. This is my old incubator that I was going to try to use as a hatcher that I have been talking about where I have to have the thermostat set at 105 to get it to 99.5/100 inside....so it has me nervous that it is all of a sudden going to decide to work "right" and then spike up to 105. I've read many reviews about this particular incubator having a tendency to temperature spike randomly for long periods of time. I was also beckoned by the hubby to help go move cows, so didn't want to risk cooking them for an hour or more. I got home 2 hours later and it was down to 97. So adjusted it back up to 103.5....and now it is a pretty steady 101 in there.....so off to go adjust it down again and try to find it's new "sweet spot" for temp. I should have a new still air hovobator on the way this week. (I'm not going to stress myself out trying to get this thing to work any longer than I have to.)
