Pullet eggs are always smaller than normal eggs. It would be highly improbable to have a first timer laying bigger eggs than all your other established hens, regardless of color change.
Thank you for posting the picture with the soup can. It's helpful to put the color of the egg in perspective. Since the red in the can of soup is pretty spot-on with the red on my cans of soup, I can only assume that the egg itself is not nearly dark enough to be a marans. It sucks, but she will lay eventually!! You want her to be a slow layer, as the egg travels through her body the dark coloring is applied, ergo, the more time it takes, the darker it will be.
Here is my marans (not cuckoo, nor hatchery) first egg. It's hard to see, but it's a paler brown (still darker than any other egg I've got) covered in very dark brown specks. A week later, her eggs are more evenly colored in the characteristic dark brown of the marans breed.

This picture is her first (left) and her third (right) egg. The lighting sucked (late afternoon, almost sunset) when I took this picture, but I was trying to get a comparison shot of the speckles.

Thank you so much for posting those pictures. After seeing those, I am sure that the eggs are not from her(the marans) but from the BO. I guess her eggs are just changing in color and size a bit which is fine by me!
