Strange egg

I got a strange egg from Pearl this morning.  She didn't quite finish applying the shell to her egg.  That circle/spot is about the size of a pea.  When I collected the egg, I thought it was a piece of pine shaving stuck to the egg.  But I soon realized that it was just the inner egg membrane.  The rest of the egg appears to be just fine.

I've read numerous articles and blogs about odd eggs.  It appears that if you have hens long enough, you'll eventually get an egg that just wasn't quite right.  I don't think there's anything wrong with her. She is a power layer, laying 6 days a week.  Which is pretty good for a Buff Orpington.

I think she ate too many tasty treats in the garden yesterday and didn't get quite enough calcium to finish up her egg.  So maybe I'll give her a calcium rich treat today such as Greek yogurt.  Or maybe I should scramble up this egg for her and her sister and give her a special treat.
