If I'm not mistaking you are talking about a red tail boa correct. If so, I would suggest two hides but don't be surprised if she does not use them much. My little boa just recently started going inside of a hide for the first time recently and many people say that thier boa uses hides when little but not as much as they get bigger but still offer at least one anyway. You could clutter it up as much as you like and if there is a reptile show near you then it may be a good place to pick up a variety of things such as vines, hides, fake rocks, etc., and you won't have to pay much for shipping. I think boas tend to be less finicky (not sure if I spelled that correctly) than ball pythons so I would not worry too much about not having perfect hides. Good luck!
