Duck egg pipped but no hatch

[stanpack6]

I am hatching my third pekin duck. The eggs pipped Friday morning but still nothing (as of early morning Sunday.) you can still feel small movements and hear peeping occasionally. Under the shell where the pip occurred seems somewhat dry. How long should I give it? When should I help and how? I am new to this Humidity is at around 63-65%. Thanks so much!!!

I'd increase the humidity to 70% and give the eggs a good misting (had you been misting them regularly?). They may be stuck. I have only experienced one stuck chick and I wound up helping it after it had done a half-zip and then stopped (I waited about 5 hours before stepping in). I've never hatched ducks so I don't want to tell you when to step in. Hopefully others will have ideas.
