Day 28 air cell changed shape in my duck egg

Is it normal for an air cell to dip down/change shape during lockdown? It honestly looks like one side is saddle shaped now and it wasn’t like this before lockdown.

Yes, that means hatch time is drawing near. It dips down on one side and that's the side the duckling will pip into the air cell. Good luck with the hatch.

Thank you! This is my first ever hatch so I am learning. Just patiently waiting on this little duck.
