ok so I have the incubator running , it's been on for a few hours, so I am needing some tips I am using a Little Giant still air incubator.I have pekin and possibly pekin-runner mix eggs to go in tonight. I have looked online and some people say 99.5 degrees but the humidity is confusing. I have no way to measure it, it has 3 channels in the bottom to put water.The middle one is larger and the two-on the sides are smaller. Should I wash the eggs off first??
