My flock has gotten fowl pox. It started about two weeks ago. The first to show signs was Nannette. Nannette's head was all covered in blood this morning. I carried her in and cleaned her up the best one can clean up a chicken that is living. I put Vetricin on all her spots. I think the pox got irritated. The base of her comb is really bad. It looks like a gash. I isolated her so the others will not peck at her bloody spots. Is there more that can be done? Is there something that can prevent the bleeding from happening to the others?
