I typically have 35-45% humidity during incubation, then raise to 55-65% at lockdown (last 3 days). So, I think your humidity was a bit too high. The best way to check if your humidity level is correct for your particular eggs is to monitor air cell size during incubation. Here is a good chart for proper duck egg air cell size at different days of incubation:
If your air cells are too big when you candle, you'll want to increase the humidity to keep them from losing more moisture inside. If they are too small, you need to decrease humidity so they will lose more moisture and grow to the correct size.
This page has well researched answers and in fact is the Cornell Duck Health Page. https://ahdc.vet.cornell.edu/Sects/duck/hatching.cfm
Good luck. I'm doing my first hatch in many years and it's amazing how much research I had to do before I started. Details haven't changed much since I was a kid but I some things have changed. When I was a kid I didn't get an egg turner or forced air fan (Love mine!) and humidity was a total guess. Of course, even if you follow Cornell/Metzer farms/etc recommendations exactly it's still kind of a crap shoot. But hey, it's fun even when it goes wrong.
