The leg colour change makes sense if she went from laying to a non-laying pseodo-rooster. When a chicken lays the yellow pigment is drawn out of the skin, starting with the cloaca and ending at the beak, so good laying hens turn from yellow to white.
I have a hen that turns semi-rooster every time she moults, and a little even when laying. She crows, mounts hens, and her comb even goes from being floppy to upright. Its pretty fascinating. But she never goes ALL the way over to a "he".
In your hen's case Id suspect she has actual damage to her ovary rather than a simple hormone fluctuation. It could be from infection, tumors or some other damage that may or may not be finished. So without direction she is swapping to default chicken which is rooster.
