I have a 5 year old budgie named Risto ( common peasant name in my country) nicknamed Ricky. I have him from when he was 2 months old and seeing as he wasn't hand raised I think I have done a good job taming him, but he still doesn't trust me completely ( he is scared when i try to take him in my hand, he only stands on me). I also a have a fully untamed female budgie which i intended to breed with Ricky but for some strange reason I couldn't ( i have experience with canaries). They seemed bonded and were constantly preening each other. Now, after 2 years they are starting to fight for food and similar stuff. Should I remove her from him, because he is quite lethargic and refuses to stay out of his cage, and if so, how to do it so he wouldn't get too depressed?
