Our hen's skin is red and the feather are disintegrating on her bottom. We think it may be vent gleet (thrush) a fungal disease. In reading the "Backyard Poultry" magazine, they suggest using betadine as a treatment. Does anyone have any experience with this? We have her on antibiotics now because the roster scratched her really bad. We think the gashes are healing but now notice the condition I talked about above. We will go to the drug store tomorrow and try to purchase some spray betadine (iodine treatment). Anyone with this type of experience? She's an excellent layer and produces one egg every day or every other day.
