Hey, so I have one egg that was due to hatch two days ago (the other two weren't fertile) so it's now day 30! There's no internal pip either. I candled the egg today and the duckling inside was moving, and it has filled the egg apart from the air sack. There are still a couple of thicker blood vessels near the air sack, so I didn't want to intervene invade I caught one. I can't work out what part of the baby is near the air sack, though there is a fairly pointed bit that I'm hoping is the beak. Does anyone have any advice on what I should do or what's happening? Thanks!
