Duck eggs not hatching after day 29???

[PeachHillFarms]

These eggs look like they have fully developed but the outside of the shell is getting darker and i can see a baby inside but I'm not sure what's going on with them not hatching. Do you think they are dead? They don't smell any. Any clues.. Ideas..?

What kind of ducks, and has your temperature stayed steady throughout incubation? What kind of incubator are you using?

 

[PeachHillFarms]

Ancona/runner crosses and yes it's been at 100 degrees the whole time & a styrofoam incubator.

Mine didn't start hatching until day 29 and 30. The dark spots were a sign of baby moving. Give it two more days before you lose hope

I'm in the same boat. I have a Brinsea Mini Advance and set 7 eggs. Day 7 it was obvious two were clear so I replaced them with chicken eggs. 1 duck hatched day 27, then the next day the chickens hatched (was day 21 for them) but nothing from the rest of the ducks. Today is day 30. How long should I wait?
