What is normal time for Muscovies to get out of shell?

[Jarhead]

I am used to chickens, seem like when they pip you have a bird in a couple of hours or so. These are our first ducks. They started pipping yesterday around 6 pm, right now they are still rocking and rolling around, with some more cracks in the shells. They seem active so I am not worried. Just trying to get a feel for the usual time from pip to fully hatched.
Thanks
