I noticed this morning that one roo had his eye closed, when further inspecting the flock I noticed more of them having foaming or bubbling liquid coming out of their eyes. I was recommended Terramycin, however my feed store only had Duramycin-10. I went ahead and purchased this and have put it in their water. I notice that the ones more affected are wanting to stay in the coop. However, I am going ahead and cleaning the coop to try and disinfect everything and hope these guys get better. Any recommendations would be great. I am also making up a batch of oatmeal with lots of fresh garlic to help boost their immune systems. I really prefer doing things organic, but I guess I am using the antibiotics and hope these guys are all treatable and get better. A few of them are coughing or sneezing too, so I am thinking it might be a respiratory infection.
