How long from "shadowing" to internal pip?

What day are they on?
Do you have a picture of the saddle air cell shawdowing egg?

Okay so non-candling photo has a line with 27 next to it which is their current air sac size, not sure if it's clear in the photo -apologies if not.
Then the candling photos are of eggs 1 and 3, although they all look pretty much identical in terms of what the shadowing (if that's what it is) looks like, lots of movement, and where it's happening (on the lower side of the air sac/the side facing the table)

I totally understand. I bought call duck eggs and had them shipped recently and none of them made it. Usually have something hatch from shipped eggs.
Your eggs are making great progress and should hatch in a few days!
