Hello everyone. I just have a question, my green cheek conure Talos has been sneezing now for about 3 weeks. I took him to the vet a week ago, and the vet said that his lungs and everything sounded clear and that he looked to be an overall good health. The vet just told me to watch him for any changes in Behavior. So my question is what could be making him sneeze? I've tried moving his cage, doing a good thorough dusting of my house, and he is still sneezing. Any ideas?
