One of my hens has a very swollen foot and appears to have a small amount clear discharge coming from it. The base of her toes are also swollen. It looks similar to other photos I've seen of bumble foot but it DOES NOT have a scab. I didnt notice it imediatly becuase she was born with a deformity and always walked with a limp. I soaked it for a few minutes in epsom salt until I get more info and she seemed to like it. Any suggestions??
