Hi everyone, I'm Boba's other "parent" and just wanted to thank you all for the feedback. Boba received a shot of penicillin at the vet and then I continued to apply a topical antibiotic/anti-inflammatory they gave me. I gave her an additional bath the day after the vet to remove the remaining maggots and I have not seen any since. She has been living indoors with us. She ate a lot the day after the vet but has stopped since then, so I took her to an avian vet where they found a lump along her intestines, and they can't tell if it's a blockage or a tumor. They think that's what made her vulnerable to flystrike. She is currently on an oral laxative and an intramuscular laxative to see if it helps. The avian vet had me switch out the topical antibiotic for manuka honey so now I'm applying that to her wound instead. Here is a picture of how her wound is currently doing.
I started a separate thread for her intestinal issues here:

Thanks again for all the feedback, it was very reassuring to hear what you guys had said when I was stressing out about this.
