This started just a week ago- sneezing and open mouth breathing. She's a tiny bantam. I took her to my vet (he doesn't treat chickens, but consulted with an avain vet) and we got her on tylan for 3 days and baytril for 5. She's got 2 days of baytril left- she's done with the tylan. Vet said her lungs sounded wheezy and dry. Her sneezing has gotten worse, better and worse again. She's making a squeaking noise with her sneeze. She seemed better yesterday afternoon. This am, she's worse. I've put a call into the vet, but he's already said that this just may not work and we might lose the chicken. Her breathing is bad. I tried a steam treatment with no improvement. Poor thing. She's eating OK (she ate some peach with yogurt on it last night and will still inhale corn on the cob), but not normally. She's roosting a lot with her eyes closed, fluffed out. Anything that I should try? I hate the thought of culling this bird, but maybe that's the kindest thing to do?
