Not a marans expert, but pullets can lay some strange looking things until they get going. Give it some time to see what happens when she is more consistent.
Thanks for the response. Yea, that's kind of what I figured. I really hope her eggs darken up. I also have a Welsummer and a Black Tail Buff, so I'm hoping for some nice dark eggs from all of them soon. With my two Blue/Wheaten Ameraucanas and Blue laced Wyondotte, I should have a nice array of eggs.
