Let us know how your little one is doing. I have been hatching turkeys. Out of 2 hatches I have had 3 pip at the wrong end. The first 2 I left alone and they died in the shell. I don't think they had room to turn in the shell to zip it. When the 3rd egg did it, I figured I'd help. The 1st 2 died, so if this one died too I wasn't out anything. I carefully peeled part of the shell away, leaving the membrane. It had made a little hole in the membrane so I knew it could breathe. Then I wrapped it in a wet papertowel and put the whole thing in the bator and waited. About 12 hours it finally started moving itself around like it would if it were zipping and it hatched. That was last Sunday and it is doing fine with the other 5. I think there is a real danger with turkeys anyway of the baby actually being stuck and not able to move itself around in that small end of the egg. If your little duck appears to be giving up, I wouldn't wait too long to intervene. Anyway, just my 2 cents worth.
