Duck eggs internally pipped day 21- raise humidity?

[WhiteTreeOfGondor]

My 7 duck eggs are at the end of day 21 and at least 2 appear to have internally pipped already. The others are showing shadowing and movement by the air cell so they also look close. I took the turner out, but should I raise the humidity this early?

My last hatch in that incubator also pipped early, but they weren't quite as early as this. I keep the incubator set at 100 degrees because the Govee thermometer inside generally reads between 98.9 and 99.9 degrees when it's set that high. Should I lower the temperature back to 99.5 for future hatches, based on how early the ducklings are pipping?

Yes you need to raise the humidity any time there is an internal pip. It appears your incubator is running to warm.

Thank you! I think I'll set it back to 99.5 next time.
