I've noticed one of my chickens (a 6-week old Ameraucana) has been sneezing lately. The only other possible symptom I see would be her nostrils, which are red.
I'm fairly new to chicken keeping, I had chickens awhile ago when I lived in California, but have since then given them away due to a move. I decided about 7 weeks ago that I wanted to start again and purchased four chicks from a cool "Urban Farm Shop" here in Portland. One died a few days later, but we didn't think much of it because it had showed no symptoms before she died. Wanting to have a bigger flock, we returned to the store and bought three more chicks. A few days after, we noticed the before mentioned chick was sneezing. We were slightly alarmed, but again didn't really do anything about it. The sneezing continued, sometimes never and sometimes once every twenty seconds or so. Now ocassionally other members of the flock will sneeze but never repeatedly like the one chick.Today we took the chickens outside (their coop is not quite ready yet) and I noticed Florentine (the before-mentioned chick) sneezing again. I inspected her and noticed that her nostrils were red but no discharge really. When she sneezes its often fast and hard to catch. I'm slightly worried and I don't really know how to diagnose her, seeing that she's one of the most active chickens by far. I researched a little bit before I came across this site and I read that it could be her food or her bedding. We started the Chicks out on Union Mills Medicated Chick starter (recommended) and it is dusty. Their bedding is pine shavings, I believe. Thanks, MHAH
