Injured duck from hawk attack

[LauraWilder]

Hello! I need help. I have a duck that was attacked by a hawk and she has lost the end of her wing. The bone is exposed, but no longer bleeding. I was reading that leaving it like that to heal can lead to death through the bone dying but I don’t know what else to do.
I have given her electrolytes and some food and have her separated in a quiet area. Will she survive an injury like this? What should I do?

I would at least clean it and maybe put some ointment on it?I’m not a duck person.Maybe post a picture of it.I hope someone else can help you.Good luck!

Here’s some pictures I took this morning of her wound, the area around it is pretty warm to the touch. We tried to bandage it yesterday but she tore the bandage off so I was going to apply antibiotic ointment today and try to rebandage it.
She also keeps preening herself around the injured area along with the rest of her body, there was quite a bit of blood on her feathers and still is. Should she not be doing that?
