Behavior change in my Sun Conure
I have a 2 year old sun conure. My husband was annoyed by his loud screaming. He is bonded with me. I traded him Saturday for a more quiet green cheek conure. I then regretted my decision and got him back. He came back after 4 days and was sick. I took him to a vet & he has a yeast infection. I am giving him antibiotics and something for the yeast infection. He has improved greatly.
I am concerned about his change of behavior. He does not seem to know me as before. He no longer screams. His feathers are more orange than yellow around his neck. He bites holes in my clothes. He won't step up on my finger. He no longer says the few words he spoke before. My concern is that his temporary owner may have switched birds and brought a different bird to me. He also rolls his head around like he is strutting. Could only 4 days rehoming this bird have drastically changed his behavior? Any info will be greatly appreciated.
