Well, my concern is that it went down to 4% even though the humidity in the house was much higher. I should be able to use the ambient humidity, but if the silly machine automatically drops to 4% when it's dry (in spite of the measured house humidity being 40+) that's not going to be possible.
I borrowed a Nurture Right incubator, intending to do a dry hatch. Most of the areas where I see dry hatch being successful have relatively high humidity, so I figured it would work.
I turned the incubator on and it showed above 40% humidity when I closed the lid. Great. But as the machine...
