She's been a little lethargic for a few days but she kept perking back up so I didn't think it was serious. I'd been giving her electrolytes in her water. Tonight I decided to bring her in since she was still looking a little down and I noticed right at her lower leg joint where the feathers end, she has an ugly scab, swollen up and a few red swollen spots on the same leg. The other leg is fine. Her feet are a little cold to the touch and she's breathing heavy now, but still eats, drinks and walks around. I don't think it's bumble foot ... Could this be marek's related? I've lost some chickens to it earlier this year. Just a cut maybe? I went ahead and started antibiotics in her water once I saw the scab.
