Egg shell color change.

[lagrange chicks]

I have 1 easter egger and 5 bared rocks. Last fall they all stopped laying do to molt and short daylight. Now they all are laying again but 1 bared rock is laying a white egg, I don't see any problems with any chicken and eggs are fine also. Easter egger lays a green egg almost daily, so I know it's not from her. Is this normal? Anything I need to watch for? They get allflock and oyster shells and grit on the side.

Are you sure it's a barred Plymouth Rock?

Yes. They are 3 years old and always laid a darker egg.

All eggs start out white because the shells are made from calcium carbonate. They get their color from the hen's genetics as the egg forms. brown pigment is added at the end of the laying process, issues in the hen's reproductive system can cause a lack of pigment or also sometimes if a hen is stressed or just coming out of a molt or just getting older it can lay a lighter colored egg while its system reregulates. Or maybe her last few just had less bloom? If it went from like really dark to White that's got to be some sort of reproductive issue but if it went from like a very light tan to a more creamy color it may just be she's depositing a little less shell color at the end of the process. Out of sheer curiosity I would be interested in seeing differences if you have pictures of both
