I think the wound looks good and it's healing. I would continue with what you are doing.
Sounds like her appetite is improving as well. Coming out of the cave and away from heat, roosting on the cage and interacting - I would say she's making progress.
What antibiotic are you giving? (just curious)
I would closely monitor the crop after antibiotic treatment to make sure it's not getting sour. If it's emptying overnight, then likely that won't be an issue, but in your previous posts you have the know how to treat for that.
I hope she continues to improve. Are you going to keep her once she's healed up? I hope so
