I learned that. Quail eggs are the only eggs that have arrived hatchable. I had some cracked, but I don’t know when that happened. Considering the foam, I think it was pre-shipping. No chicken eggs have made it to me. They were mostly scrambled. I don’t mean bad air cells, I mean broken yolk and all. I know my P.O. is partially to blame.Yes, just bought some foam shippers the right size. 30 holes in a 7x7 foam block. In my experience, quail eggs ship pretty well compared to larger eggs.
Anyway... quail eggs are more forgiving and the foam helps a lot too.
