Hi there! I am having duck hatching issues. My ducklings seem to be very active and internally pipping, but can't seem to externally pip. I don't know what the issue is. My current egg ready to hatch is on day 24. It has already internally pipped. But no sign of an external pip yet. My eggs seem to do this...then die. Also, the few I've tried to help by poking an air hole have also died. SO FRUSTRATING! We have yet to have successful hatch. Current settings are 99.5 degrees and 45% humidity, which I am currently trying to bring up since my ducky has already internally pipped. is there something I am missing?
