I have been looking at all of the threads I can about upper respiratory infections and how to treat them, but I have a question about how long I need to keep her separated and on meds. A little over a week ago, I separated (aka brought inside, aka spoiled chicken) one of my hens from the flock when I heard her breathing like she was having an asthma attack, almost honking and stretching her neck to breathe. She also let me pick her up several times which is very not normal for my girls. She just acted like she felt really bad. We lost another hen a few weeks prior with no warning, but she may have had the same thing and we didnt catch it. I did treat her and the rest of the flock for worms, but I wasnt convinced that was what was going on. So I put her on Oxytetracycline (sp?) in water and the rest of the flock on Aureomycin feed supplement to try to get ahead of this in case it is going through my little flock. No one else seems to be showing symptoms, so hopefully we have it beat with the rest. My question is how long do I need to keep her in and on the medication? Her breathing sounds good most of the time now, but she occasionally still sounds labored. She is eating and drinking just fine as well. One thing Im worried about is that she is acclimatizing too much to inside and its winter in the Midwest... It has been unusually warm for December, but we are about to get hit with winter weather. Any advice would be appreciated, TIA!
