I didn't get them from a breeder.. I got them from a poultry mkt. Lesson learned. I have no idea where the pox came from but they are free ranged most of the day. He's the only one sick right now and he's been separated so it hopefully won't spread any further. I'm just glad I know how to treat and he has a chance. I only see the pox on 3 of my roosters. Two are acting fine.
