What is the ideal humidity level for incubating eggs? I have my eggs in a hovabator and the humidity level is at 70%. I have a feeling that is too low. I believe the moisture level of my vermiculite is good (clumps when I sqeeze it but doesn't drip water) plus I have a small container of water in there as well. The temp is 88-90 degrees. If I need to raise the humidity, how can I do it? Thanks.
