Thanks for the update and glad Pepper is feeling better.
As well as the other suggestions given to encourage her to eat you could also try adding some baby food but make sure it says no salt added on the label. Also the canned chicken flakes should be rinsed in water if there is salt included in the ingredients and the chicken broth diluted.
Another thing to try is satin balls...
