Hi I have just gotten a 14 week old sun conure from a breeder a week ago. I work with him everyday at least an hour. The bird shows a lot of aggression when inside his cage. When I look at him he will fluff up and hiss along with lunging to bite. When I play with him he doesn't bite but will sometimes hiss at my face when he's on my shoulders. He has learned to step-up but only outside of the cage. The breeder showed me how to train him to stay on me and for the most part he stays but after a while will try to fly somewhere else. I just don't know how long it takes for him to stop seeing me as a threat. What else can I do?
