Should I be worried about this egg/hen?

[Eryniel]

One of my girls just laid this egg today, should I be worried? I believe it’s from my blue Marans who is about a year old. Their nest boxes are about hip height, and I found this egg in the boxes, so that gritty stuff isn’t dirt. There haven’t been any changes recently in the coop, so I don’t I’m not sure what’s going on. The pictures are attached:

Any ideas??

Chickens have an "oops egg" once in a while, so i would just keep watching her closely and make sure she's getting enough calcium. Besides that, I wouldn't worry.

Yes and also make sure she has a water supply at all times and make sure she is on a consistent food diet.
