If you just picked her up last week, she is not even close to being settled in. The cage looks a little too arboreal from what I can tell. Even though ALL carpets are semi to highly arboreal, you still want something that will accommodate your snake when fully grown. Bredli are one of the larger, heavier bodied species and from what I can see in the pictures your cage is really tight.
The hides probably don't differ in climate a great deal and seem close together. At least in the pictures they do.
By all means buy THE COMPLETE CARPET PYTHON ! It is a fantastic resources and it cover almost ALL species of the morelia family and very in-depth levels.
That is a nice looking snake.
They actually use hides, but to answer your question, they will ignore them too. They are confident snakes and for whatever reason, the carpets will often lay out in the open with no fear. I always like to give the option of a couple of hides. Whether my coastal will bask on top of them or go inside them depends on the phase she is in.
This coastal, female is a 6+ footer and she is in a 4 x 2 x 2 foot cage. She is not using her hides here. She is a little over 2 years old.
Carpet pythons are one of the best display snakes around.
Your cage looks very nice, I'm just concerned its a bit tight.
Enjoy that animal! Its a beauty.
