If all of you husbandry is correct it could just be a curious snake. While most bps stay in their hides all the time there are exceptions. My friend has had one guy since august and he is always out crawling around, the only time he is in his hide is after he has had a meal.
Check your husbandry:
-Warm side 90-94
-Cool side 80-84
-Humidity 50-60%
-Two identical hides.
-Consistent day/night cycle.
