Is the duckling deceased?

[HighMeadowFarm]

We recently incubated muscovy ducklings with 3 eggs left but I believe they have died.
2 hatched 3 days ago at day 31, these guys looked fine when going into lockdown, still had veins but today I candled them and I think they unfortunately have passed.
Please let me know your thoughts.

Look closely for movement as you are before the estimated hatch time for Muscovies.

Muscovies should take around 35 days to hatch. Hatching at 31 days means either they are mules. (Muscovies crossed with Mallard derived ducks) or your incubator is running to hot.

I am not able to see movement or veins
