Internal pip 48 hrs ago.....

[Juno's Chicks]

I have a Swedish duck on a nest of 6 eggs. First noticed 5 were internally pipped Sunday night. Don't know if it was longer than that. It was 2 days since candled last. Yesterday one 1 was pipped and tonight 4 are. The other 2 still have movement in the egg. I do not hear any peeping and haven't yet. I'm thinking today is day 35. Let them go or externally pip????? This is the first broody bird we've had and we've never hatched eggs!! Thanks in advance!!!!!!!!!

I believe ducks take longer than chickens to hatch, but I've not hatched any myself, so I'd suggest you look here:

This is a very good thread about waterfowl incubation, helping ducklings hatch etc. It also explains what to look for when you candle an egg to determine if the duckling's ready to hatch. Good luck!
