Hi, I just learned yesterday that if you give a parakeet a mirror they are harder to train and probably won't speak. After I read this I removed my boy parakeets mirror. That had explained why he will sometimes bit me and possibly why he doesn't speak. (Although when I first got him he hit is head against the wall 2 times, could that give him brain damage?)But here is the only problem. He is 4 years old and has had the mirror or 3 of those years. I think it would be cruel to take away his buddy or 'mate' after 3 years but I really want to become closer with him and I want him to trust me more. Also, is there a reason that he doesn't like swings and only climbed his ladder 2 or 3 times, or does he just not like to play with those type of things?
