Ok update. Her actual limp leg showed signs of swelling and yellowed skin above the hock. *Nothing to do with the other foot's lil' bumble.

I ordered some Fish Mox and after the 2nd day she was acting like her old self, wanted to leave her quarantine, and is standing around even wile eating. The limp is still there but after the 5th day the skin is returning to normal color.
It looks like the limp (and no weight bearing) may be there to stay which is a shame because of course she gets jumped by a couple other chickens and tries to stay alone. After daily visits back into population, she insists she wants to stay an inside bird next to my desk but I need her out.
Any thoughts?
