I have a 2.5 year old Sun Conure name Phoenix. We have had him for 2 years and he has never really been nice. I make sure that he has toys, a big cage, freedom to play on a playground (outside of cage during day), good food, and fresh water. He has two cockatiels (who do not share a cage with him) to interact with. Phoenix will attack anyone that gets close to his cage and will try to swoop down onto my or my son’s head and bite us. I feel like I have tried everything to get him to like me... At this point I don’t know what to do with him, he’s just mean.
