Hello, help, my chicken has black spots on her comb and waddles, n more tail feathers. It's been 100 degrees on the CA central coast. I caged her separately to watch and till I find out if it's contagious. Other 14 chickens are fine. Will get iodine to clean sores. She seems to be acting normal. Shes the mother hen, probably not peck marks. will watch consumption and droppings. Any ideas? Is separating her necessary? Thanks,CC of Cali
