Oh my. All that moisture canNOT be good. I'd drill a 1/2" size hole in that lid pronto, if I were you. Or two holes. Open it up, dry the inside of the lid to remove as much as you can. I doubt your hygrometer is accurate at all - condensation like that is near 100% I think. I could be WRONG though. It's just what I'd do if it were my incubator and my eggs.
