New to hatching - viable?

[Geranium]

I picked up two fertile muscovy duck eggs to put under my broody pullet. I candled them when I got home. Am I correct that only one of these is viable? There is visable movement in the reddish egg.
Thanks!

Second egg is developing. First is either not viable or at an earlier stage of incubation.

The first one is weird and blurry. I'd say it began incubation later or died early. Any possibility of the former?
