Any help or advice would be much appreciated.... I posted about a week ago regarding my 6 month old hen that is having vision problems. She's definitely not fully blind but it's fairly significant. No cloudiness, no discharge, her eyes are dark but her pupil seems normal and reactive. I've had her isolated in the house just over a week now and she's been eating/drinking well and seems to have a peppy spirit overall. The only other symptom I noticed upon bringing her in was occasional "gaping," maybe 1-2 times in a span of an hour. No other resp symptoms. After a quick search, I was off to the feed store to look for a dewormer for possible gapeworm. Unfortunately they didn't have the right one. The clerk asked about her symptoms and questioned whether or not she actually had a resp infection and recommended terramycin ophth oint and vetrx. After a day or two, I actually thought maybe she was seeing a little better and I also thought I the area around her eye looked a little different and was worried about fowl pox for a day or two but after nothing else appeared that seemed less likely. Over the last few days, it seems like her gaping has become more prominent and I honestly became much more concerned about starting a dewormer and put the ophth oint and vetrx on the back burner. I was finally able to start fenbendazole 3 days ago, although I think yesterday was the first time she got down the full dose. She's still gaping but no other signs of resp distress, no wheezing, I might have heard I tiny sneeze this morning after I took her outside to dust bathe. In addition to treating her, I'm deworming the rest of my crew. I've actually noticed one or two others gaping in the last few days as well. I've also heard a few different chickens sneezing a lot more than usual but it's been raining quite a bit here. The only thing that concerns me is one of the chickens that has been sneezing is now ?coughing. She had a high pitched almost seal like bark last night??? I haven't noticed anyone else with the mild eye irritation around the eyes or scratching. And I think everyone seems to be seeing ok. Again, if anyone has ANYTHING that might be helpful, PLEASE share your thoughts-----thanks!!
