I candled the my egg that has the comparatively large air cell. Now it looks like the chick is pushing up against the membrane by the air cell when it moves, but has not internally pipped. I'm not supposed to lock down until the morning - should I do it now? I tried to upload a video, but can't figure out how.
Definitely watch it, and listen for it! Almost every hatch I know they are pipped internally before I ever see the first pip. With the aircell so big, they can be malpositioned, they have a hard time getting into the right position..I hope that isn't the case, even though I have had plenty pip on the wrong end too, and zip themselves just fine. Hatching is such a funny business!
