I found this fascinating. An experiment where a fertilised egg was taken out of its shell and matured in a glass. They actually succeeded after many tries and the video is just mind blowing, IMHO. Goes for 10 minutes.

It is interesting.
But for a moment there, I thought after all that effort they were going to feed it to the cat.
perhaps they should have tried bantams because they hatch in 18 days and are generally pretty hardy.

A womb with a view!
That is indeed fascinating and possibly a bit cruel but it would be good to learn more. Eggshells are semipermeable, allowing some water and gas exchange with the outside, and feed the birds calcium: it kind of looked as though they completely sealed the glass.

I thought the stuff over the top might be cellophane, which has some similar (semi-permeable) qualities.

Could be.

It’s been many decades since chicken eggs have had a viewport cut in them to watch embryo development in real time.
I checked an embryology book from 1949 and the technique was not available then, so more recently than 70 years ago but, still many decades ago.
But this it the first I’ve heard of growing a chicken embryo completely out of the eggshell. Apparently it’s very hard to do.
Acetic acid will dissolve eggshells leaving the membrane intact, but they haven’t used that so presumably that’s too violent a chemical.
Given that the calcium coating of a chicken egg is the last layer to be added, perhaps you could arrange for chickens to lay shelless eggs?
Next step, growing a placental mammal completely out of the womb.
