Did you have them tested ?I'm curious about how my flock got it. I bought them as day old chicks from Meyer's. Only one shows any symptoms so far and that was a couple of months after they were moved from the brooder in the house to the coop outdoors. My neighbors near by don't have poultry, the closest seems to be someone who has ducks about a quarter of a mile away which I can distantly hear on occasion. I do have lots of quail that come through my yard and hang out by the coop so it seems like mine caught it from wild birds unless there's a better chance a breeze brought it from those ducks. Thoughts?
