Good morning!!! My Ancona ducks are hatching. They are pipping and zipping, but the membrane is becoming hard pretty quick and they are having a hard time getting out. I have the humidity at 65. Should I make it higher. I have some runner duck eggs that haven't pipped yet. Tomorrow will be day 28. Do you think with a rest they will break through that zipped membrane. They must be missing a few parts of the membrane while zipping. I have them in egg cartons, so they are upright. Hope this is not too confusing.
