I have one hen who suddenly began making a rasping/honking sound while breathing both in and out. It was very loud in the morning but decreased throughout the day till it was a light rasp while breathing out only. She would occasionally sneeze a loud chirping sound.
She exhibits no signs of illness (no discharge, full energy, eating and drinking well). I took her to a vet who saw no signs of gapeworm. We concluded that she had inhaled something but has since probably gotten rid of it yet her bronchial tubes remain now swollen and irritated.
The night before she began making the sound I changed from a pelleted feed to a powdery mash. I believe it was the change in feed that caused her to inhale a small piece and develop the problem. Just wanted to put this suggestion out there as the OP's description fits my experience very well, especially the effectiveness of the natural brochodialators.
