Recently I bought my parakeet toys designed to hook outside of her cage and perch on. I hooked her cage open so she would be able to get to them easy. However, I didn't know where to start in helping her realize she can come in and out however she wants as she pleases. I started with getting her used to the toys first, and now she'll stand on them for a short while before climbing her way back into her cage. I've tried tempting her with treats, but she never fully commits to coming out. She is fully tamed, and has no trouble with coming out to play when I help her. How can I teach my parakeet to come out of her cage by herself?
