She's stressed and is trying to get away to a safer place.

If I read you right, that enclosure is 10'x5'x5'??? That is WAY too big, even for a full grown female Ball. These snakes prefer smaller spaces and a good enclosure for an adult would be 3-4' long, 2' wide and no more than 12" tall. They are not climbers and don't need shelves or tall branches, just nice low branch bundles for exercise and shed assistance are enough.

Please, post some pictures of the snake and enclosure so we can advise changes from there. But if those measurements are correct you REALLY need to get either a 30 gallon Breeder tank or a 41qt(6" tall) or 90qt (12" tall) plastic tub ASAP!
