I have a 5 year old Quaker, jade that has become a mess. About a year ago he started plucking and being very aggressive. He is on a pellet diet has lots of fruits and veg. In fact right now he has melon and bell pepper to munch on. I have changed out toys, and hid treats around his cage. I don't know if he is a boy or girl! He will step up then climb to your shoulder but after a few minutes he bites you. We put him back in his cage when he does this. He chatters and says about 5 words. He has also become cage aggressive. He is our only baby so he gets a lot of attention. Thinking back I had a cockateil that died about a year ago. He was not in the same room as jade. And they were never together. I would be open to getting another bird if that would help jade. Any suggestions would be helpful
