Okay, first we had Miss Belle come down with something. We did loose her. Tried antibiotics and nursing her back to health, we were too late. She did show a few symptoms, then RAPIDLY decreased. We are new to having chickens. So this is a learning process, and we want to do everything we can to get this under control and have happy, healthy girls. Now two of our other girls are starting with the first symptom we saw with Belle. They keep one of their eyes closed. They are both able to open their one eye but keep it closed. No ooze or gunk , just closed eye. The are all eating and drinking good. We keep a clean coop and pen, fresh water and food. Kitchen scraps for treats. We just started putting acv in the water about a week ago. Since yesterday, with Penny (cochin) and one of our Easter eggers (not named yet) showing the issue with the eye, this morning I put antibiotics in the water. Please tell me if I should be doing more......................
