Ok I need help again. One of my buns has this large, bleeding lump on his hind foot. I'm assuming it got a cut and infected before we knew about the cut. How do I treat this? I've separated him from the rest of the litter while they are out grazing since he's gotten blood on their backs. Sigh. I don't want the poor thing to suffer and I don't have another cage open to keep him separated from the litter overnight.
