I'm sorry this happened to your duck but glad you had a vet to treat her.
If she's wearing a bandage on her neck that may be whats scaring the other ducks...because all new things are scary
If she can't have one of her friends with her you can try giving her a mirror to keep her company.
Is she eating any kind of treats at all? If she is you could always try giving her some treats in a small bowl of water , may encourage her to drink and get her to eat something.
If you do need to tube feed but haven't done it before it sure is scary. But once you've done it a few times it's not bad at all. I had lots of help here for my 1st time as well.
