Shells seem nice and firm but one of our girls just started laying these with this funny discoloration pattern in the past few weeks - think it is anything to be concerned about? Prior to they were always uniform in color. We have 8 chickens, variety of breeds, all just over a year old and typically laying 1 a day.

Anyone have any idea what might be going on with my girl laying these mottled eggs? It’s just been the past couple weeks I’ve noticed it, they are all just over a year old and generally seem quite happy and healthy!
