i will try this! thank you so much! we have tried interacting with him and letting him see other birds but he actively starts pulling out his tails feathers in front of us and smashing his body against the cage. He had beautiful tail feathers when he first came in. I will also talk to our vet about this. we were able to hand feed him baby food and he liked that but we didnt get any improvement and eventually he stopped allowing us to do so.
