Welcome to the forum Icarus
Sorry to hear about ChiChi.
Even tho she was scared of people, I'm sure you loved her all the same and I know how much it hurts to lose a pet. I have 1 who is still scared of people too, but I love him to pieces and it would kill me if anything ever happened to him. He is who he is, and I'm sure that's how you felt about ChiChi too.
Like BLR said, this is probably a good time to work with Rocky and spend as much time as you can with him. Be consistent and patient with his training and maybe you can finally form a bond with him. Maybe some day down the road once you have bonded, it would be a good idea to get him a friend. But for now, take your time and be his best friend.
You've certainly come to the right place to learn and talk about keets.You learn something new every day here! LOL
Hope you enjoy this place as much as I do.
BTW Got pics? We LOVE pics
