Congrats on your new critter. It sounds like your temps are dialed in, and since it's only been a month that you've had her, I don't see any cause for serious concern just yet. If she's 6 months old, and at a healthy weight, she can go quite a while without food. I think you're doing the right thing by leaving her totally alone except for cage maintenance. I'd space out the feeding attempts to every 2-3 weeks until she decides to eat again and they ALL eat eventually. I'm a firm believer that the hunger ALWAYS wins. Unfortunately, BPs can be some of the most stubborn snakes and playing the long game with them can be frustrating. I've had them go 8-12 months without food and they were just fine. It's just a pain for the keeper. Best wishes and I hope she eats for you soon.
