Chickens & ducks take up to 24 hours from internal pip to external pip. Chickens take up to 24 hours from external pip to fully hatched & ducks take 24-48 hours. Relax, be patient & let them do their thing.
A broody will usually sit as long as she can feel life in the eggs under her. So there should be no problem with a chicken hatching ducks that would take 28 days instead of 21.
Okay I'm about to go into lockdown and have a few questions. I know to stop turning on day 25, but if I set my eggs at 4:00 in the afternoon do I turn up until that time? Also, some look to maybe pipped internally do I continue to turn those? They are ducks and day 25 starts tomorrow at 4:00pm. Thanks!
What position are the eggs in? (vertical or laying down?) I personally wouldn't turn them if they have internally pipped...but I don't know nuttin' bought nuttin' cause I'm brand spankin new at this, so take that with a grain of salt.
