Alright so basically, I ended up with 3, 17~18 day old duck eggs. They are in a homemade incubator, were kicked out of our ducks nest and cold. Two of the three are moving, the third one I cant find any movement. Have been doing fine in the homemade incubator for hours. I keep checking the temperature (my first time doing a hatching) and they are all normal except, the duck egg that has had no movements temperature is always higher then the other two's.... Is it most likely dead?
