I'm with you.
I kept the schedule that the breeder had and fed my snake on day 2 at her new home. She ate like a champ, even being she was at the beginning of a shed cycle.
Don't handle your snake for 2 weeks??? Give it time to settle in??? I handled mine for the first 2 days for about 15-20 minutes each day and she seemed fine. I did wait until she came out of her hide in the evenings before I picked her up. She did not ball up or get all tense. She seemed to be quit curious. I was not able to hold her for about a week after feeding because her eyes turned blue and she was well into her shed cycle, so I did follow that rule.
Clutter the cage. Really? If she is out at night and seems to be surveying the territory don't you think she is ok? I do have 2 hides, fake plants, and some mopani wood, but the front is pretty open so that I can watch as she crawls by. She seems to sit and watch me at times as well. Not with her neck in the familiar "S" shape, but actually stretched out as if she is being nosy!
I just try to read my snake and make changes only if she seems disturbed! If you pay attention they will let you know if something is wrong.
