Exactly what he said. Putting paper on the outside of 3 walls will make her feel secure. As far as putting her in the bigger tank I put my male in a 48x26x12 enclosure and cluttered it up a little and I can tell he is happier and he now eats better. All bp are different so you may not see the same results as me. Defiantly use 2 of the same hides with an enclosure that open and big, lots of fake plants and stuff to. People that don't use hides or only have 1 hide have there snakes in a tub in a rack so they feel secure already. With regular enclosures like I said above they are more open and they need the security so another hide on the cool side helps them cool down there body temp without being exposed. If they don't have that option they may stay in the hot hide and never get the chance to cool down bc of the lack of security. If the rock hide you have isn't snug on your snake she won't feel secure either so if it's to big you may need to buy or make a snug fitting hide and wait until she grows into the one you have. Another option is if the rock hide is a little big you can stuff it with sphagnum moss or news paper to make it more snug. As far as the coke box one not being sturdy there's tons of things you can make hides out of, just be creative! Sounds like your doing a good job, more questions you ask and more advice you take the happier you and your snake will be!
