Day 26 on Ancona duck eggs, locked down at day 23/24 because of lots of movement...everything looked normal yesterday but today 2 of my eggs have air cells that cover the entire side of the egg!! One appears to be internally pipped (I think, pics below) but is it going to be able to turn with an air cell so large? These were shipped eggs and they were upright the first week but then the air cells were stable....What do I do at this point?
First 2 photos are one egg, lowest pencil line on first photo is where the air cell was yesterday, trying to show what I think to be the internal pip in the second photo, third photo is second egg....movement at edge of air cell but I don’t believe it is pipped (excuse blurriness, my son took pics while I candled)
Try not to worry, it looks like the air cell has just drawn down which is part of the hatching process. If you can see an internal pip everything sounds on track.
Air cells drawing down is explained here ~ https://www.backyardchickens.com/threads/goose-incubation-hatching-guide-completed.491013/
I know it’s geese but it’s quite generic for waterfowl.
Good luck with your eggs!
