You might also think about adding one bird from the flock to the separate area for the injured girl as a buddy.....
....if the mingling doesn't go well.
Time for some chicken juggling, might take some time and a lot of observation, hopefully you have time for that.
More info/pics on your flock and coop/run might help us give you more specific solutions to try.
