Wow, look at Honey’s bright and happy little Face!!! After so many pictures of her back end, it’s so great to see her cute expression!!!

I am really happy that she’s doing well; you’ve done an excellent job with her!
The cut feathers won’t regrow until she molts, but I think I’d still leave them alone. You could put something like triple antibiotic ointment on irritated skin, but I’d probably just leave it all open and clean.
Unfortunately, I expect that her flockmates will pick at her back end, which is a problem that I’m wrestling with right now. I’ve tried a few different anti feather picking lotions to try to discourage the behavior. One of the chicken wound ointments like those would be another thing you could apply to her irritated skin...
