I recently got a year old RIR rooster. He seemed to be fine the first couple of days. Last night my girlfriend noticed that he was breathing like he had a cold. You could hear fluid in his lungs. This morning I noticed that he wasn't acting right. Upon closer examination, one of his eyes is watery and almost closed. There is a crusty yellow substance around his mouth. He is breathing through his mouth and there is a few yellow spots in the back of his mouth/throat. He was walking about around okay and doesn't appear to be weak. Anyone know anything about this?
