Nor do I! I just hatched for the first time two weeks ago and I think it was pure luck we got 6 chicks out of 24 eggs. We kept our Little Giant incubator at about 45% humidity until just before lockdown, then went to 66%. We had one egg that pipped and chirped for four days but made no progress, sadly, but we agreed not to interfere or assist but let nature take its course. I can only imagine that 85% humidity must put hatching at pretty long odds, and wish you luck.quite frankly haven't got a clue!
