Aww, so no movement or response from that guy? So sorry. :/
I've actually never done the float test, just regular candling. Can you see any movement at all in the others? Look at the edge of the dark mass inside the egg, you should be able to see tiny movements if they are alive in there. Are you candling in a very dark room with a strong flashlight? That helps alot to be able to see what's going on, and the light usually wakes them up and they tend to "dance" a little in there. Do you still see any red blood vessels at all? Are you able to post pictures of the eggs during candling? I know that can be tricky, but it might help us tell what's going on. Can you also post a pic of them just sitting in the incubator so I can see the discolored one? That usually means it has died and is rotting in there. You can also do a quick sniff test of the one that is getting darker. Does it smell bad?

and one of my eggs, the majorly discolored one, has what looks to be blood ring with no movement. After taking these out, my incubator has returned to the normal duck smell (tehe!), they did float during a brief test, and vessels are not obvious to me. Still hopeful I might get one little ducky out of this.
