Hello from the greater Cincinnati area. I started keeping chickens early this spring and have loved every minute of it. I have a mixed flock bought from a local feed store and everything has been going great. My girls started laying in mid June and had an alltime high day of 13 eggs a couple of weeks ago. Three weeks ago I brought home a rooster, after a week I started noticing some of my girls were sneezing/snorting. After two days most of my girls were doing this and I had one die. Egg production has dropped to about 3 eggs a day. They are still eating very well and are acting pretty normal. However the nazal discharge seems to have gotten worse and they still are sneezing. Only the rooster seems unaffected. I have been reading about diseases and am still not sure what this is. I would appreciate any advice. Just one other note, there has not been any unpleasant odor associated with this nazal discharge. Thanks again from me and my girls.
