Your seeing lice on her, treat them with a Louse Powder or something with Permethrin. Bugs can weaken a bird. (DE is not going to treat an active infestation)
You don't mention your location, but that would be nice so products can be recommended.
I would feed her her normal feed along with some egg. Give her 400IU Vitamin E and 1/4 tablet B-Complex once a day.
What Percentage protein is the grower feed?
Check to make sure her crop is emptying overnight. Provide grit (crushed granite) free choice so she can process foods.
