DUCK EGGS NEED HELP PLEASE

[ozark hen]

I have a mallard hen sitting on some eggs which I think belong to the muscovies. Not the color she always laid.
Now I think we are into week 4..not real sure..and I just went out to check on her and the eggs. The eggs have visibly changed. Almost like I can see the duckling curled up inside. Kind of weird, almost see through. Is this normal? I stole five of them and put them in the incubator with lots of water. Now what? Are they about to hatch? I read where some folks were misting them? I never hatched eggs before so I could use some help here please? I put a sponge in the bator and pored about a cup of hot water into the bottom of the 'bator.

Don't mist them. Muscovy take 35 days to incubate. It is a long wait for those. I would have waited to let the mallard hatch them. Ducks do it better than we can.

If the ducklings are not pure bred they will be stertile. I have always been told a muscovy cross is a mule duck and not fertile.

thank you Miss P.
Edited to add:
I took your advice and returned them to the duck. Too soon for me to be grabbing them. I am not sure that these eggs belong to her...I know for sure the guinea egg doesn't LOL These eggs were a different color so I am suspecting they belong to the muscovies but I could be wrong. Infertile muscovie eggs can be a good thing. LOL I hear they multiply worse than rabbits? I have nine muscovies now and two mallard hens. Something happened to my drake one day. I miss seeing him take off with the hens following him and making huge circles around the place before coming back. The hens don't fly around anymore sad to say.
