Duck hatching help

[Kimberley2010]

My duck eggs started hatching yesterday. Came down in the morning to see 2 pipping. They were chirping. 1 till lunch time yesterday and 1 until last night. This morning none of their holes are bigger and they have both stopped chirping.
What should I do.i was successful 2 years ago hatching duck eggs. I'm forgotten how long they take and advice I have read is so confusing. Neither are zipping and I really don't want to hurt them. Do you think they need intervention?
Thanks so much

Ducks can take a good 48 hours to progress. If it doesn't seem distressed and the membranes don't appear to be drying out, I'd give them a little longer.
