Symptoms
In young birds, the first symptoms are sneezing, gasping, and often droopiness. It is in this stage of the disease that it closely resembles infection with bronchitis. After the appearance of respiratory symptoms, deaths occur in a flock in quick succession and it will increase numbers from day to day.
In adult birds, sudden deaths occur in a few instances. It is followed by a number of birds showing respiratory symptoms. The affected birds are depressed with ruffled feathers. The symptoms are also accompanied by diarrhea, which is the passing of a watery stool with an offensive smell. Also, there is a chance of profuse salivation. The saliva often accumulates in the mouth and obstructs respiration, which results in the production of gurgling disused birds that may be soft-shelled and deformed. In adults, it may cause dullness, loss of appetite, and other minor symptoms.
