On Wednesday I swapped a couple of my silkie roos for a couple of girls. About halfway home my daughter heard one sneeze. When we got home I transferred them from the carrier to a holding box for isolation. I noticed the smallest hen that was sneezing had an unpleasant smell. Not knowing anything about bird illnesses, I didn't give it much thought. Just figured she had been cooped up in a small carrier for several hours during transport and she needed some fresh air. I saw her sneezing but no discharg. Thursday morning I looked her over and told she was stinky but noticed her eyes and nose were clear. She was alert and eating/drinking, but still sneezing. I decided to get some VetRx and by that afternoon her nose was crusty. I cleaned her up, dabbed some VetRx on her comb and beneath her wings. Neither of the other two showed any symptoms. Oh, I also thought she felt warm to the touch too, like she might have a bit of fever. This morning she had a bit of dried mucous on her nostrils and it looked like one of her eyes was a bit watery. I decided to run up to TSC and get some meds. This is when I started asking Google to give me anxiety. Iended up not getting anything for the chicken but it was several hours before I got home. I checked on her and saw that all her symptoms were gone, including the sick-smell, except for the sneeze. The other two birds I got with her do not seem to have any signs of whatever is going on here. So....how do I know if this is the dreaded coryza or just a run of the mill bad weather bug?
