I have a hand raised ring neck parrot. He is just starting to get his black ring and has become very aggressive in the past 2 weeks. He seems very territorial. He is usually very tame and quiet. What could be causing his aggression? I have tried handling him more but he doesn't want to be held at all.

Did something happen to him? Did someone hurt him?
