I have an 48 eggs digital incubator, auto eggs turning. I don't know why the humidity level is too high. The digital display shows the the humidity level is 92%. If I open up the lid a little bit, the humidity drops down to about 75% but the temperature also drops. Has anyone have a similar problem like mine? How can I lower the humidity down to ideal humidity range 60% or 65% without affecting the temperature. Thanks.
