It's been more bc of water or thermometers moving around that I opened it so far. (For the most part) yesterday out of the blue it spiked to 111* on one gauge and 106* on the other. I panicked and opened everything up to try and cool it down some. It was likely only a few mins but that's the worst of my burns origins. *sigh* I am no good at this.You have to stop opening the bator. Those eggs need to have a stable environment and with the bator being opened all the time it will keep on fluctuating. Try to do as much as you can from the outside. I actually sterilized a piece of wire that I can stick through the vent holes so I can move things around if I have to. I use tubing and a syringe to add water if needed.
