This hen doesn't seem to have any scab or marking that I can see, where the initial injury would have occured.
I can check again when I get home from work.
For about two weeks now, My hen has had a large swelling in her foot. I'm assuming it's bumble foot, but there is no visible scab. The swelling is also visible on top of her foot. She walks around holding that foot up. Laying eggs fine, eating and drinking as well.
