If the wound edges are holding together well with the steristrips it should heal okay.
As for your Queen B, some rats are like that. I have a neutered boy here who adores his 3 girls, but will try to KILL any other rat he meets, female or not. Lovely Rizzo was wonderful with her 2 sisters...a real sweetie, they didn't even have scratches on their nakie selfs which is so unusual with 3 girls. I figured she would be an easy introduction...nope. She said No More and she's actually bitten and scratched me up when I had the smell of other rats on my hands before.
I would remove all newbies that are setting her off so no more injuries occur especially with the nakies having no fur protection. I think that cage is now capped, with your girl making the decision.
