My Silkie rooster, Jake, has a swollen toe. Vet thought maybe mites and treated him with Antibiotics and shots but the toe is still pink and swollen. Vet is not a chicken expert. The toe nail fell off. Does anyone know what might be causing it and how to treat it? He was this way when we got him, it gets bigger and smaller with cold water soaks- causes him to limp at times because it hits on the spur.
