Hello, This afternoon one hen (out of four) was wheezing and hiccuping. The hiccuping kind of sounds like a "barking." Her backside seems to be pulsing a little- like she is trying to push something out. But i'm not sure about that. NO OTHER SYMPTOMS. So, no runny eyes, nose, or mouth or anything else abnormal. Except, her crop does feel like a hard ball. She is not eating. The wheezing is getting constant. I medicated their H2O with an antibiotic. What is this and what should I do? The Olive Oil thing I can try- but I am so afraid of not getting it in the right place in the throat and killing her. Thanks.
