Chicks hatched-Ducks did not!

[khall3]

I had chick eggs and duck eggs in my incubator together. I hatched 95% of my chick eggs, but my call eggs developed about half way and stopped. What could this be?

Ok, you probably already know this, but I like to eliminate the obvious first--duck eggs take a week longer then chicken eggs to incubate so did you give them enough time? Were the duck eggs shipped? Also, I've heard that call ducks can be tough to hatch, I haven't tried them myself, but maybe you could try posting in the duck forum for more specific advice on calls.

Yes, the calls had 28 days and they were not shipped. I only mentioned the chick eggs to show it was not a problem with incubator. I'm very frutrated as I have not hatched a single duck egg.
