We just bought our first chickens recently, we love them BUT one of our ladies had a shank (ankle area above foot) injury due to a band the farm had on it to identify her age. They took it off but it has really cause her whole foot and ankle to swell and the shank/ankle and scale area to growing around the band for however long they had it on her. It almost looks like a deep cut, she limps really badly, favors the other leg and tends to want to sit around all the time. She is not as active as our other four chickens. What can we do to help it heal or should we return her. I kinda am attached to her already, we nick named her limpy Lucy.
