Hatching runner ducks.

Hello just looking for some advice.iv done this before but it was years ago.but these weren't due to hatch until the 27th may.i noticed 3 days before that they had internally pipped.so I stopped turning them.the day after this they externally pipped they aren't due until tomorrow.but they have been pipped for a couple of days with no progress.i can see one of the beaks through the hole its made and that ones chirping.the other have made either 1 pip mark and the other 3 but like I said no progress today.Im spaying them every 3-4 hours the eggs are moving around so they are still alive.humidity is 88% and temperature is 37.5 looking for advice really thanks in advance.

Hi, I am not a hatcher, but I am thinking your humidity is too high.

Let me see if I can find something more specific. And is this relative humidity or wet bulb?

Yes, please, please drop that humidity now.

Please read about it here.

Your littles may have some trouble with that - like, serious trouble.

Its only 80% though and on my incubator information sheet I got it.said 65% or more I only turned it up when they externally pipped.
Thanks
