HELP! Facial Swelling, Sneezing, Coughing, Raspy, Nose Discharge, Watery Eyes and Lethargic .... But NO Smell. I don't think we are fighting infectious coryza because there is no smell coming from any of the chickens, but whatever it is, it is VERY contagious. Our once flock of 50 healthy birds is now down 15 and counting everyday. We have only been chicken farmers for less than a year so we are very new to all this. Since the outbreak, we check them every morning and evening and when we find a chicken with any symptoms we put it in quarantine. We had to put down 5 because they were so congested they could hardly breath. With the others, we have them quarantined and trying a round of Tylan 50. We are extremely torn between the choice of culling them or trying to save them. We don't want to loose our entire flock, but we also don't want our chickens to be carriers of this illness either. Any suggestions of what we could be fighting and how to treat it? Thank you in advance for any feedback!
