I noticed yesterday that my black Silkie rooster had sores all over his head and around his comb. I searched the net and Fowl Pox is what best describes how he looks. One of his eyes is swollen shut and has white pus in it also. What can I do to treat it and the rest of my flock. I am going to inspect all the other chickens this a.m. to make sure there aren't more that have it. I would appreciate input from anyone that can help me out on this. I have no idea what to do to treat it...this is my first flock of chickens and they are 7 months old.
