I also think that baby looks too wet and sticky. Is he doing OK???
.....and 80% humidity also seems way high.
I have an old Dickey (but I love him anyway... lol sorry couldnt resist). the temp stays at 99 and humidity stays right at 50%through out incubation. I candle them and mist them 1-2 times a week. I dont do the cooling off thing (although they obviously cool some when I candle them) and since the incubator rotates them I dont hand turn them either.
on the last few days I put the eggs ready to hatch in a styrofoam table top bator, and have humidity in the 65% range and mist them and candle them at least once a day.
The mold in the incubator is not good, but if you consider the dirty nests the hens set on, and how clumsy they are, I dont think you have to worry about over handling them or mold harming the egg. Those shells are pretty tough!
