Hi there and
to the forums!
Phil has given you excellent advice. You should remove the toy and rearrange her cage, as well as being sure to rotate different toys in and out of the cage so she's always exploring something new and isn't so fixated on the one toy
Meanwhile, be sure to read through the links provided above by FaeryBee to ensure you're up to date on the best budgie care practices! If you have any questions after doing so, please be sure to ask as we'd love to help
