It is amazing how the skin will granulate in and heal up so well that one might never know how severe a chicken's injuries were to begin with.
I believe you mentioned scratch grains on the previous page, which is an ok treat for her, but with the healing process going on think of the scratch grains like candy or treats. Alone they will not provide enough nutrients to keep her strong through this process. Her regular feed has (or should, I don't know what brand you have) added vitamins, minerals, and nutrients that grains alone can't supply. I realize you probably don't plan to replace her regular feed with them, just wanted you to know ahead of time that they are less nutrient dense than her feed.
You are doing a great job and in a few weeks you will be amazed at how far along she will be.
