Is this a pigment issue? Should I be concerned?

[Fluster Cluck Acres]

My blue hen (who may or may not be a Rhode Island Blue) lays these eggs occasionally with with what I think is a pigment "spot." I know it doesn't impact the egg for eating, but am curious if I should be concerned. The hen is about 10 months, is one of my more prolific layers, and behaving typically. Is it just "one of those things" or is there something I should be looking for?

This video is the same egg as the first image. It was difficult to see. The second image shows a speckled egg she laid last week.

Some hens just lay odd eggs.

I once had one whose eggs were pixelated:

The lighter and darker rings came and went, but every egg she ever laid had that uneven color distribution.

How odd. I get a lot of ombré colored eggs. My ISA Browns laid them as they got older, but now my younger girls - 1 wyandotte and 1 orpington, always lay eggs that start darker and end lighter. I admit I do love being able to tell which hen laid which egg.

No need to worry about it! It’s just what happens sometimes. And sometimes you’ll find eggs with spots of hard lumpy calcium. These 4 eggs are all from the same bird, sometimes it just varies!
