sorry, i asked a similar question but about chicks. these are ducks (all mallard derived) it’s day 28 and they seem to still be living. they’ve had this sized pip in them for quite a while. it’s three different eggs that are all about the same place in the hatching process. thanks for the help!
Ducks can easily take more than 24 hours. The membranes are starting to look dry, but not critically yet. I'd give them a few more hours. Unless they get really brown and dry, try to be patient. Especially the wrong-end one.
