Muscovy duck off the nest at night day 17 - chances of eggs surviving? UPDATE! Ducklings hatching!

Hi. I have a handful of muscovies. I am letting one sit on a nest of 5 eggs. Last night, I put a divider between her and the other ducks. It was a thin divider - just something so she didn't get upset by one of the other ducks who she detests atm. I lock my ducks up at night and they have to share space with the broody.
Anyway, there was an apparent scuffle and she was off the nest - I'm guessing most of the night. The divider fell and covered the nest. Yesterday would be around day 17. Is there any chance the eggs are still viable?
She is back sitting this morning. Just wondering if I should destroy the nest or let her continue to sit.
Thanks.

 

Ooh I do hope she hatches at least a couple of those eggs. Thanks!

 

Good to hear because I would hate for her to sit all this time and nothing happen.

 

Thought I would come and update this thread. The other day I came home and 1 of the eggs were out of the nest and half broken with a duckling inside. It was still breathing and so I attempted to keep him warm, but he didn't make it through the night. I probably should have removed the rest of its shell, but I didn't know what I was doing. I don't understand what happened or how it got there.
Fast forward to today and by my calculations day 36 - she has one hatched duckling under her, 1 egg where it's beak is peeping out, and 2 others that I can't tell what they are doing.

 

The second one has hatched, one of them looks like it's ready and I'm not sure about the 4th one.

 

The 3rd one hatched. She's yellow too. The 4th one - I can see there is a fully formed duckling. I didn't hear anything when I picked up the egg. The egg seems soft so I guess I'm waiting to see what that one does.

 

She's still sitting on the egg. When I checked her and put it back, she slipped it back under her. So I assume everything is ok?
When she started sitting I had 2 eggs that I had gathered and they were left in a warm shed for days. She had 3 under her. I then put the 2 thinking the hatch rate might not be good. I really only want 2 more ducks.
So, although we lost the 1st one - she's not doing too bad. I just wonder if this last one was either one of the 2 that I had off of her nest or one of the firs 3 that I allowed her to actually sit on? Is there anything I should watch for Besides her leaving the nest?

 

Here's that one yellow one with the black spot. Amazing how it took over her whole head once she dried and fluffed.
Edited to say:
I just looked at the earlier pics - maybe this was the first one that hatched, but I thought it's body was black. Now I'm confused.

 

I just went out and was able to look at all of them at the same time.
The one in the pic above does have a black body. The yellow one with the patch is doing well. Didn't hide from me and nibbled at my hand. The 3rd one is all yellow. Still waiting for the 4th one. I'm not seeing any progress. I have read it can take some time. I can see a foot and maybe the beak. I didn't hear anything when I picked it up earlier.
Does mom lead them to food and water? I've placed a shallow dish of water near by the coop in the run. Should I move feed to an accessible area for the ducklings?
The original muscovies I have, I got as week old ducklings so I had them in the brooder.
