I have two pekins who each way 10 pounds. One practically drags on the ground her carriage is so low, and one looks much slimmer and normal. I was so surprised to learn that they weighted the same!
Maybe you should observe her and see how she reacts. She will quack or appear anxious if she's feeling lonely, and in that case you can add the female that seems least likely to pick at her and observe to see how that goes.
Until she heals you might want to figure out a way to separate the injured duck with a female friend. I have a situation with female ducks where one has her feathers pulled and I am having to keep them apart unless I supervise. It's a hassle but it's the only way for me to protect her for now
My pekins Penny and Puddles coming out of the bathroom by themselves because they couldn't wait for transport. Puddles is wearing hobbles as she was getting over splay-leg. I love their baby voices!
I agree, what's not to love about ducks - especially pekins!! When I was a kid I had a female pekin and male mallard and he used to also chase me and bite me - I guess protecting his female. Maybe yours will tame down a bit when you have them all together. Sounds like you have a good plan for...

Oops - my first comment "isn't there something you can get" I meant to delete. Seems like she might just need a little dab of the ointment at first then you can just let it heal on its own. The main thing is keeping her away from the feather-puller. Sorry you're having to deal with this...
