I recently adopted a second U2. He had been a breeder for a while, then sold to a couple in TN who kept him outside in their garage in a home-made wire cage for three years. I really love his personality. He is extremely calm and surprisingly trusting. I didn't have any anxiety about bringing him into our flock because he is not a needy bird in the usual way. I didn't think he would be so seemingly scared of being indoors, though I can't believe now that I didn't consider it. I don't know if the things I think he needs are actual needs of his. What I mean is that I am used to cockatoos displaying at least twice a day, being vocal (talking, singing, etc)throughout the day, and moving around. 'Zilla (new U2) just sits there. He is sooooooo quiet it is a little unsettling. Now I am aware that most people would think this is nice, but to me this looks like he is not happy. So I have changed my way of thinking about him from a "very independent bird" to a "very needy bird" because I think he needs confidence and other things. Is it a bad time to start clicker training?? Am I projecting onto him feelings he doesn't have or ...??????? Can anyone provide feedback?
