X2 on Lady of McCamley's post. Don't have much to add.I think I read somewhere that it can take up to 48 hours from pip to hatch? Is that right? I think @gullinkambe hatches, let's ask them. Oh, another one that hatches is @KF0002 maybe they know.

After I started incubating and hatching duck-eggs, chickens are a relief to hatch for me. Muscovy ducks are notoriously unnerving to hatch, especially in an incubator. They can go many days from internal pip to finish, which means bigger risks of shrink-wrap, suffocation etc. I usually do a lot of assisting there.
I personally don't do broodies anymore, incubation is just easier for me. But when I did, I always isolated them in small houses on the ground and away from others. I've had ducks hatch in the duck house, and it was chaos. Eggs stomped on, got too cold because mom removed all the bedding, and dead ducklings that got away from mom and froze to death. Baby birds are very fragile in their first day alive.
How sad so many of them died!
I think a lot of difficulties with broody-incubation comes down to the environment. We, as their providers, can try our best to make it as natural and easy as possible. Lots and lots of good bedding, enough space for mom to move around the nest, no interference from other animals etc. Good luck!
