First off, if she is pooping then she is eating. Also if you have the means, weight her; if she isn't lsoing weight then she is fine. Another thing may be to try another flavor (provided you're using a two partmix) maybe she just isn't into the flavor you chose, the good thing about CGD is that there is a plethora of flavors. You could also try feeding live I would sugest either nice gutloaded crickets or some B. Dubais.
