If you have two perches, put one toward the top on one side, and put the other toward the bottom on the other side. That way she can flit or fly from one to the other.
Hang some of the toys from the side of the cage. She can play with they that way too. I would take all of the toys except two or three out. Then you can rotate them in and out so she won't get board and she can have more free space in her cage.
Does she only have one perch or she is only using one perch. My guys like their rope perches best of all. They are really nice because you can bend them around any way you want.
Be sure she has perches lower in the cage so that when she decides to explore around she has places to go.
