Looks like excessive calcium or bloom, she's not spinning her egg in the shell gland during spray booth time.

Spinning her egg in the shell gland? What does that mean? Sorry I’m ignorant i guess.

Spinning her egg in the shell gland?

The egg turns(I think) in the shell gland while shell is being formed and coated.
Might be I was just making a play on words.
ETA. OK, the egg doesn't actually spin in the shell gland, so inconsistencies of shelling and coating may be because certain parts of the shell gland work better than others...but, I really don't know, sorry.
I think it's explained in this excellent video, which is worth watching regardless:
