Its really great that she's eating and drinking, thats awesome progress! Looks like your on the right track, just out of curiosity, what is in that antibacterial spray?
Looks like you cleaned it well, is she responsive, moving at all? To start, its important to make sure she's recovered from shock. Don't add Applecider vinegar, its not helpful unless you want to try to keep algae down in your waterers, and I'm not even entirely sure if it really helps with that.
Put sugar in her water instead. This will help her recover from shock, and
@azygous and further explain its benefits. If you offer sugar water, always make sure you offer plain water as well. Make a wet mash with her feed as this will be easier to eat.
As for cleaning the wounds, rinsing them with Saline, Veterycin, Chlorhexadine, or diluted iodine is always good. If you don't have any of those, warm soapy water works good as well, which it sounds like you already washed with. Nice work!
You'll also want to apply a THICK layer of
pain free Neosporin. Pain relief isn't good for chickens or ducks. If you don't have it, any pain free antibacterial cream will do. You want to have a thick layer at all times to keep it moist.
Clip any feathers away from the wound that may hang into it or irritate it. Don't wrap. Make sure to clean at least once a day, and keep a close eye on the wound to prevent infection. Poultry are very resilient, you'd be surprised what they can survive. Sounds like your on the right track, keep up the good work for your sweet girl.
Keep a close eye on her, and make sure she's in a calm, temperature controlled environment were she can relax. I've always dissolved 1/2 a baby aspirin in water, or popped it right down my poultry's throat for pain relief. Thats for chickens though, not for ducks.
@Crazy Maizie, were is your research for the 5 aspirin? I'd be hesitant to give that much.
@Wyorp Rock and
@Eggcessive will be able to provide you with additional information. Azygous who I tagged above will be helpful as well.
