The Blue Copper Marans is not in the Standard but basically they should be like a Black Copper except blue where the black is. That said, your bird is young and will change. Her eye color should be bay and it looks pretty light in the photo, but can continue to change until laying age. She should have the copper color only on the hackle feathers and to the top of her head, but not down the breast like she has. There should be a slight slope to her back from neck to tail, her back should not be level (can't really tell from the pic). She appears to have excellent leg/foot feathering. Ideally, the blue color is a medium blue, not too light or too dark, with well defined lacing on the feathers. She should have a nice well rounded breast and width to the back, tail should be at a 45 degree angle. Ideally the underfluff color is grey, not white. Hope this helps. She is pretty, the main thing I see with her at this point is too much color on her breast.
