The thing about the half log hide is it has two entrances, and that's why we never recommend it to people.
I wouldn't move any of my BP's to another enclosure, while sure some people do and it works for them it's not going to for everybody. I would never recommend it to another person simply because not all BP's will eat when being moved from their normal enclosure and a BP will eat in it's own enclosure if it eats from being moved as well. That's all that they're saying ROACH.
You want to give the snake a thermal gradient so it can regulate it's body temperature the way it wants to. Depending on the size of your snake try a mouse hopper(but only if it's a good meal for the snake). I don't see your snake and pictures can lie so I wouldn't attempt to judge size by a picture. Some snakes will never eat f/t but then some will switch to f/t once their feeding response has kicked up. So while you're trying to get your BP to eat, I would stick to live until she's eating regularly for you or at least two meals.
