Brown spots on quail eggs seem to be rubbing off

[sjhart18]

I'm day two incubating coturnix quail eggs (off white with brown spotting) and some of the brown areas, especially around the blunt end, are kind of flaking off in tiny particles?? it happened just from turning them, and out of curiosity I rubbed a spot a little and it was very rough. I’ll attached a photo, I’m just so confused. Are my eggs okay?

Normal. Abrasion can cause this to happen when the egg is still wet. Running a freshly laid egg under water can wash the entire pattern off, leaving a white (or blue) shell.

Thanks so much!
