I just got a now young hen that seems to cough every so often and has a slight clear runny nose and her eyes look just a little watery. Otherwise she seems healthy. I did not notice this until she was here for a day. I just separated her from our other chickens, so that they don't hopefully catch it. Wish I would have confined her first now!!! I should have known better. Anyways, I am planning to get some antibiotic to treat her and see if this helps. If I can clear up what she has though, will she definitely be a carrier of whatever it is for life. That is what I am reading when trying to figure out what respiratory ailment she may have. I would want to put her back with our other hens that we will keep for their lifespans, but will they catch what she had, even if she is better then?
