I would play it by ear. Check and double check your husbandry. When a bp roams around during the day, or more usually than normal, it is usually a sign that there is stress. If husbandry is fine, then your snake may be hungry. In my opinion, it doesnt hurt to try again tonight. However, make sure you are feeding it an appropriate sized meal.. 10-15% of your snakes body weight or if you dont have a scale, it should be around the same thickness as the thickest part of your snake.
