I live where it is very dry. It's normal to only have 15% relative humidity. I have my bator inside my house. I recently incubated 4 eggs (my first time) to try it out. I could not get my thermometer to read more than 50% humidity and I tried everything. I filled the well in my still air incubator, put a 9" round pan with water and 2 large spunges that I kept wet in there. I don't know if my humidity reader is accurate, it is digital. 3 of the eggs hatched all by themselves. 1 did not. I don't see any movement and it seems to be stuck to the shell. The others hatched 4 days ago. Does anyone have ideas on how to raise the humidity? Do you think that 1 egg was just not meant to hatch. It did keep up with the others during incubation when I would candle it. I think I just lost it close to the end and I don't know if it was a humidity factor. I need suggestions. THANKS!
