Low light, two hides and waiting a week, even two with no disturbance should help.
Nothing wrong with a smaller, live prey item to start things off when you do feed again.
I have a male retic that isn't a year old yet that goes 10-14 days between meals and has struck and refused before too. ALL species of snakes will refuse food at certain times. I'll bet she eats soon enough.
The time span from the arrival at your home, the first and second attempt at feeding was relatively short and may have added some stress to the move and acclimation.
Don't handle, don't disturb and wait a bit. I know that may be difficult but the snake will feel less threatened as an end result.
It isn't a bad idea to contact the breeder and find out the exact setup they used for the snake before shipping. You may want to mimic that if things don't pan out.
