I noticed this a few days ago, and was hoping it would clear up but it seems to be getting worse. It looks bigger and more like a scab than a chicken pox bump. One of my other chickens had the pox about a month ago but cleared up with time. Those were flatter. This is big and bulbous. Infected? Its black, and looks like it spread to her bottom "lip" too. Anyone had anything like this? She is a OEG self blue bantam, 3 months old. Thanks in advance for your help!
