To deal with this, you can try relocating her cage and completely re-arranging the inside of it. If she has a Happy hut, remove it because this will also stimulate egg laying. You will notice that she will shred anything that even resembles paper. This, too, is normal. Try offering a couple of new toys for her to play with.
Swings are excellent choices.
Good luck with your lovebird. She is now 7 months old. She becomes aggressive when I put my hand into her cage. But she is fine when she is outside her cage. Two days ago, she found her favorite spot in my bedroom.
