We noticed one of our leghorns limping and when we caught her and took a look she has a swollen foot with some clear bloody discharge. There isn't any visible trauma and the bottom of the foot is clear ruling out bumble foot. We have had chickens for over a year now but are newbies with first aid. We cleaned it, applied neosporin and wrapped it. She is separated from the flock. Anything else we should do? Any help is appreciated.
