You may want to post the tank set up and size to help people think of ideas. Sometimes beardies glass surf because their tank is too small or their environment isn't stimulating them. An idea of what is available in the tank may help too as well as heat set up. It would be good to know when her last bowel movement was as well just to check that off the list. Since she is a "she" do you know if she may be wanting to lay eggs? You could set up a dig box and see if she becomes interested in it. I've only had male beardies but I know some females have had problems laying eggs. Some bearded dragons are going into brumation around this time which can affect their eating and sleeping habits. My beardie is going through this right now where he is sleeping more, eating less and I soak him every few days to keep him
hydrated and well as encourage him to use the bathroom. (You don't want them keeping their bowels full and during this time they may not be active enough to pass it themselves). Those are the some ideas I have but I'm not an expert! You could always call your local reptile vet to see what they say or take her in for an exam. Hope this helps a little!
