You could set up a separate 'see but no touch' area for her and the other new hen for some weeks where they would be able to eat, drink, dustbathe and rest without getting picked on by the other hens but still within sight of each other.
Feed should be available for them all the time so she can eat whenever she feels the need and regain strenght.
