My 5.5 yr old hen I believe has a respiratory infection. Both of her nostrils are crusted hard and plugged. I have tried to use peroxide, warm water with a little bit of dish soap, and nasal mist using a qu-tip . Nothing seems to be working. It seems to make it harder for her to breath after I'm done. I have her on antibiotic and vitamins for almost a week, she seemed to improve somewhat. How long can it take to clear up an infection. Any suggestions on how to unplug her nose. She is eating and drinking. thanks
