My 4 years old chicken had a symptom of fowl pox since 4 weeks ago. It initially appears to be a wound at her comb and near her ears, since it was bleeding. I applied betadine 10% for 2 days, but it worsens (it grew bigger and there was more bleeding) several days later. Since last week, I noticed that her fowl pox virus started to increase substantially when a lot of warts appeared on her wattles and other parts of her head. I know that she had fowl pox when she was 1 year old. So, she should be immune to it, and if it did occur because of stress, she shouldn't have the symptoms since 2 weeks ago. The other chickens in the flock, doesn't have the same illness as hers, and they all had fowl pox before they reach 2 years of age. I seperated her from the flock and I applied betadine everyday since 6 days ago.
