Normal bp behavior. How long have you had her? How old is she? What type of enclosure is she in? What are your husbandry numbers? Temps, humidity and ambient. How hot is the hot spot? Four weeks is not very long for a juvenile or adult but it is if she is a young bp or a hatchling. Check the hides, maybe you need a smaller , tighter hide for her. Make sure she has fresh water and a bowl to soak in. Switch your substrate to cypress mulch unless you already use it. Wait for her to adjust to the new substrate for 3 to 5 days. Don't try to feed her for at least that amount of time. Good luck.
