I've been putting iodine on his comb every day and vitamins/electrolytes in the water as a couple people on here suggested but it seems to be getting worse. the orange bumps are spreading and getting bigger and turning black, swelling then popping open and bleeding.does it get worse before it gets better? is there anything else i can do for him? he doesn't seem in pain but it just looks awful. so far its only him that's got it.
