I have 3 Easter eggs, 3 buff orpingtons, a barred rock and Cochin. A couple days ago I noticed one hen sneezing and coughing. Day before yesterday she and another had their eyes shut and a discharge bubbling from their eyes as well as the one stilli coughing. I put some clippings from the mower in there because they love the grass but other than that nothing has changed. Can anyone here help me?
