I would have thought the same, I've left mine in the ground for 2 or 3 days before digging them up before because I was too busy, believe me, I have zero finesse. Mine are now chalking up. I wouldn't worry about it if they haven't chalked yet.No. That you'd already answered the part about how long until chalking happens.
In a CAMP KEENAN video, he states that even a one or two day old ebryo can be damaged if you rotate an egg. (An egg layed 1 or 2 days ago)
I had also thought that that would happen much further along into the development.
