    When we moved to Xenfora some of the signature options didn't come over. In the old software signatures were limited by a character limit, on Xenfora there are more options and there is a character number and number of lines limit. I've set maximum number of lines to 4 and unlimited characters.

So children can be born from frozen embryos.

But can little chickens hatch from frozen fertilised chicken eggs? Or are they too big?

I would try and look it up but my brain is scrambled.
 
No idea. But chicken egg <> embryo; the embryo is inside the egg That is, freezing the fertilized chicken egg would be akin to freezing a human womb with the embryo inside.

I'd bet that a chicken embryo could be frozen then thawed much like is done with human embryos, but they'd have to get it out of the egg first, then back in another egg, without destroying the egg in the process.

Summary

A simple method has been worked out forfreezing and storage of chick embryo fibroblastic cells. Cell suspensions were shelf-frozen at −75°C to −79°C, stored in the growth medium, and supplemented with 10% dimethyl sulfoxide in polypropylene tubes. More than 90% of the cells which were stored for 220 days were still viable after thawing.

*The investigation was supported in part by Grant E-553 from the American Cancer Society, Inc. to H.H.L.



So it's possible, but it's not exactly "freezing a chicken egg", it's "freezing the fibroplastic cells".
