I'm pretty sure @WVduckchick did, and there was someone else but the username slipped my mind.

I did have one on the side of a quail egg. At lockdown, I saw alot more clear area than I hoped, so I pulled it. Left it out for 2 days, but opened it today and it was well formed. I'm honestly not sure if I killed it by pulling it, or if it had quit before, but I expected a difficult time for it. The air cell was fairly large comparatively.

Can you go later??? I don't think I could stand that knowing they were at home hatching!
