1. feed her healthy diet.
2. give her a good running wheel and foraging cups (some night time treats.) and few toys for her to play with.
3. a proper sized cage.
THAT will make a great start to a good owner.
4. give her some days. Then give her some weeks. THEN give her some months.
do your bonding stuff, read about different ways and tricks, if she spends enough time with you she will eventually learn you are not a threat and she will stop crabbing at you.
YOU and specially STELLA need time.
