Welcome Dustin and Shelly!
Dustin if you don't mind her company let her be with you. Alex will help me do everything. He just rides around on my sholder and watches everything I do.
You can teach Shelly to play with toys buy having her with you and you playing with them. When she see you playing it will perk her interest. I make most of my toys and Alex loves to "help".
Also Alex can be pretty ruff when preening as well. Not always but sometimes.
Give her time she will come around. It just takes work on your end but it will pay off, and one day you will have the bird that you know she can be!
