Embryo dead inside egg? Day 26

[Conolii0316]

I candled my duck egg on day 26 and saw that the duck inside wasn't moving. I gently shook the egg, but still saw no movement. I put the egg back in the incubator still hoping that it's alive. Is it normal for a duck egg on day 26 to not move, or is it dead?

They're babies - they sleep a lot of the time. Not seeing movement on any particular candling would not be of concern to me.
