Hi, I have a chicken who had an issue with a prolapsed uterus. I took her to the vet who cleaned everything up and sewed her vent closed with loose stitches in case I needed to loosen them to enable her to pass an egg. Fortunately she didn't need me to do that but in the process of healing, she was putting her weight on her hocks. She now has what appears to be bumble foot in her hock. I've scrubbed it with betadine and removed the scab and tried to remove some yellow stuff with tweezers but nothing came out. Her hock is swollen and appears to be sore. This poor chicken has been through a lot and the only reason why I've gone to this much trouble is because she has a zest for life and has been fighting the whole way along. She's still eating and is now in a separate cage with a towel to sit on. Could this be bumble foot? Any suggestions on how to treat it? Thanks!
