I don't have any experience with this, but I would suggest leaving her alone for a few days. Falling is probably very stressful on a Ball Python. Don't freak out just yet.If she seems fine and eats fine on her next feeding day then I wouldn't stress too much. Just be sure if you're holding her you support her with both hands. Do not let her hold on to you without your support underneath her, she won't feel secure and this can cause unnecessary stress. We learn from our mistakes! Good luck and congrats on getting your first BP!
