Injured duck advice…already went to vet- just worried about my ducks mental health

Well as the title says, my sweet evil duck Quackthulu, was mauled by a dog. We’ve taken her to the vet where she got staples, pain meds, antibiotics, the works. She’s been inside in the “duck hospital” which is about a 5 by 5 pen in our spare bedroom, with water food and clean puppy pads ect.

So we’ve been applying the cream the vet gave us twice a day, as well as the antibiotics and pain meds.

It’s been over a week, and she’s started really getting pissed, I mean she’s attacking the hell out of us. She’s pacing, she’s huffing and hissing. I’m really worried about her state of mind. We have another appt at the vet in a few days but I’m wondering has anyone dealt with this before? She’s never been this PISSED and obviously she’s in pain but I was wondering maybe being inside is doing something to her? I opened the window so she could quack to her friends outside and the communicated, but I’ don’t know what else to do…. Is this common ?
