If her eyes are sunken in she is dehydrated. She is probably also malnourished and calcium deficient. Soak her in a deli cup with very wet paper towels for several hours and then mist her often and provide a water dish until the dehydration improves. You can soak her once or twice per day if her eyes don't quickly return to normal.
Continue to hand feed her by placing drops of CGD on her nose and letting her lick it off. Sometimes they shake their heads to get the food out of their mouths if they do not like the taste of it, but keep trying because she may start to eat it after a few tries. You could mix it with some organic fruit baby food to start if you have to in order to get her to eat more readily. Try to get an organic baby food that does not have any sugar added (and don't use anything that has citrus in it--I might try peach). I would add a very small amount of the baby food to the CGD mix and see if that helps--the less the better but you can add more if needed and then wean her back off of it. It is important that she get the nutrients from the CGD, so you want as much of it in the mix as possible.
