I would probably trim the 'downward' pointing feathers you spoke of in the skin, just so there's less weight on the skin trying to heal, and it won't get knocked as much
i'm worried about that hole I see... It looks like they've taken off her sphincter/cloaca. I don't know how she'll go holding in anything (pooing/laying normally).
also the bit of flesh hanging looks kind of tubular, it's not coming from inside her is it?
