I got the juniors recently, but I put them out at the three week mark just as we got 12+ inches of rain folliwed by a cold night. They got snotty the first night out so I messed up by putting them in a dog crate in the main coop thinking about it being so much warmer and having a floor so it is not damp, but I was not thinking about the adults getting it. Newbie mistake. I just thought they just got chilled and when I asked the advice was to let them try to get over it since it was not clear what it was. I will likely try to pull the one other hen that I think was sneezing this morning and treat her too. Did you have to cut under the eyes like I read in the link above?
