My Rhode Island Red has a scabby looking thing growing on her head. People said it was a 'Pox Scab' and to treat it with iodine and it would go down, this is day 3 of treating her with iodine and it only seems to be in diffrent places. I can't tell if it is actually going down, but she seems to not like it. Should I be worried? What else can I do to help her? Is it the wrong desiese I think it is? Pictures hopefully soon to come.
