I have one duck egg that has pipped. And one that has been peeping but no pip. It is day 27. This has been going on since Monday afternoon. Simply put... what do I do? ****Now it's day 28 and I still have the same scenario 1 pip and 1 peeping/no pip. It's been 48 hours. The pip that egg #1 made is no bigger. I can't see it's beak. I can hear it and see it moving and it seems healthy. At what point do I interfere? With egg #2: No pip, and it's no longer peeping at me. I can hear it pecking but it's a faint tap now.. not aggressive like it was yesterday and the day before. How long can it live on just the air sac?
