Chirping
Ours seem to keep going and going. We started hatching on Friday night and just had two more tonight. (And several in between - we're up to 12/19!) If you hear peeping, maybe you should let them go? I don't really know, of course, but if they are alive then that seems hopeful. I also saw an article here on BYC about checking for viability if it's been several days past with no external pip. This was in the assisted hatching guide...
What breed are the ducks you hatched yourself?
I would have to say mutts
My boys are 1 large Peking and one white call
For girls I have 5 khaki, 1 Swedish, 3 mallard, and 1 white call
My male mallard flew the coop, but some of these could be his
