Okay I have a flock of 21 chickens. only around 5 don't seem to effected. I know the cause but I don't know what exactly is wrong. Over the winter the waterer went bad it started leaking and there was nothing I could do. I know you need to keep the bedding as dry as possible, well until I had the money, or my parents felt like buying new waterers their was nothing I could do it was either no water or wet bedding. This was a daily thing. I would clean it up but within a few minutes it was wet again. This went on a few months. Anyways FINALLY got some new waterers. So wet bedding was the problem and it has been eliminated. Now the chickens some are sneezing and weezing a bit though for most it isn't to bad their is ONE who sounds terrible. She sounds like she is crying and sneezing every few minutes/ seconds. What can I do for her. I am thinking of just dosing the entire flock. She was fine yesterday well other than occasional cough or something but when I posted on here no one seemed to care and the one person who tried to help made it seem like it wasn't a big deal. One reason I stopped coming on here. But seriously I am desperate my girl sounds terrible and I don't know how to help. I am thinking its respitory can I treat it as such? I had a girl who had it earlier this year and she recovered but I think it came back again. I don't know what else to tell you other then sneezing, wheezing, some open mouth breathing though not to much other then from the one hen. They all drink, eat and act normal. Could it possibly be some version of a cold? It is winter here and many of them have bald butts due to the fact of an over aggressive rooster. He has been separated. Anyways please help!
