I have a chicken with a pretty bad case of Bumblefoot. Just by looking at her foot you can see it's puffed up around her toes and then when you pick her up you can see the distinctive black scab on her foot. Me and my mom tried to help her by removing the scab on it and anything that looked like infection but eventually it started looking like white stringy stuff so we thought it might be her tissue so we bandaged it up and put her back.. A day or two after she had gotten it off but her foot wasn't as hot from infection and looking like the swelling had went down but today when I checked on everyone she is being lethargic She literally looks like she's sad. The other chickens are running around doing whatever and she just kind of sits there or walks around a little bit.. I just need some advice on what's possibly going on and what I should do. Anything is appreciated !
