I have 4, aged 2 and 3 week old Black Copper Marans I bought from a local breeder. He said they are from a breeder of the Wade Jeanne line in GA. I am wondering if it is normal for them to feather out some white on the tips and fronts of their wings. I think it is normal since I looked up some photos and it seems that others have as well. When do they change to all black/copper? They do have feathered shanks.
