I had both dry and wet pox go thru my flock - probably still is going thru it. And that’s what I wanted to bring to your attention. Don’t be surprised if others shows sign of the pox - in days or weeks. It moves slowly. Dry pox isn’t a big deal but if you see signs of wet pox - and you’ll need to check them for that - it can be more serious and you may need to take additional action.
