Do Cayuga take longer? (Hatching)

I'm sorry, Kiki. So strange that none made it.

Perhaps if you try duck eggs again, put the temp just a little bit higher? The slightly lower one may have been okay for the shorter chicken gestation, but too low for ducks?

The temps and humidity is what I've always done for any duck eggs and it has always been fine for me. Plus they have always hatched on time. This was just the first time it's happened differently.
My dad is thinking that maybe had to do with the lady's duck eggs. Because all other duck eggs, I have hatched from my own flock.
The only time I have ever hatched from someone else, is when we had a broody chicken hatch out 9/9 eggs that I had bought.

What in the world happened?

I am so sorry it sounded like it was making such good progress

I'm not sure. I was peeking through the window every so often to check on it and it seemed like it was almost out.
I came back around 11:30pm and found it dead

I'm just going to stick with hatching out from my own flock from now on. It always seem to work better for me.
