Peroxide and Betadine are both fine for initial wound cleaning or for later cleaning of a really filthy, pus-filled wound. They both, however, destroy new skin cells. Use them once to get the wound clean and greatly reduce the number of bacteria in the wound, then don't use them again unless real nastiness occurs.
It's always best to avoid systemic antibiotics if possible, if only so they will still be effective if you really need them. Besides, which antibiotic would you use and why? No point in giving one that only kills bacteria in the gut when you have a skin wound, or only kills germs that are unlikely to be present. We know Neosporin contains antibiotics (3) that are suited to topical or skin germs. And yes, once you give a systemic antibiotic, you have to treat for the treatment with probiotics and sometimes other care.
The flap will likely fall off or just dry up into a scab, but it is possible that it will grow back onto her body, at least at the base of the wound. Either way, it's an ideal wound dressing. The area will be covered well enough with feathers that I doubt you'll be able to see it without examination, but there may be a bare spot under there, or not.
You've got the wound clean, and she's eating and drinking, so I'm betting she will be fine. She will conceal that she is in pain but it's probably not bad, especially with the Neosporin, as it takes a lot of the pain out of a wound because of killing off surface bacteria as well as the ointment keeping the air out.
The main thing that will heal her now is her own healing abilities and your good nursing care -- keeping her comfortable and well fed and hydrated, and keeping the wound clean.
BTW, the pain killer in Neosporin will not hurt a chicken. What you should not put on them is pain killers of the "caine" group, which some topical antibiotics contain, and which is what OraGel contains. Examples: benzocaine, novacaine, solarcaine -- you get the idea. The problem with them in chickens is that they are very sensitive to these drugs and it is easy to overdose them, even kill them, with a topical application.
