I'd hold off for a few days on bathing her but clip those feathers back so you can keep an eye on any maggots that may hatch. If she has deep wounds. Just for now spraying with the Veterycin right now. Be sure to read instructions before spraying her. You might have to just do like you did before wet a paper towel and rub it close but not on her wounds. Bless her heart is she eating and drinking today? Plus clipping feathers back will keep any from getting closed up in the wound while it's healing.
Alright, thanks for your help. I'm extremely grateful to see that the flies only got to one of her wounds, but go figure it was also the deepest. I'll have to be cautious they don't migrate to the other wounds, if they can. I'll make sure to clip back any feathers that cover it for a clear site to watch for maggots.
I was thinking the same thing about putting the fly repellent on a paper towel so as not to get it in her wounds. As far as I know she is drinking but I haven't seen her eat. We're moving her cage (as we are able to) much closer to the house since the flies don't seem so bad where we currently have her. I'll put fresh food in there then. I'm considering getting nuchridrench as someone else brought up in case she won't eat to help her get some nutrients.
Right now, we just got home from the store so I need to go outside and take care of her. Hopefully the flies haven't found her here, too. We have fly netting and traps aside from the spray we plan on using to keep them away as much as possible.
I live in Florida and I don't quite know if where I am they are considered evasive, but I hadn't thought of that so thank you very much for the reminder. She has a fighting chance I believe and I will be very diligent to make sure she gets better.
She really is a little star. Honestly, for being a wild bird only mildly used to me, she has struggled far less than my domesticated ones when I have had to treat them!

Although the poor girl is probably in pain and possibly still a little shock.
