She is full from all of the crickets. Stop giving her crickets until you can see that she is eating the CGD. Some geckos will even hold out for crickets if they know they are going to get them and not eat their CGD. 5 crickets every other day is a lot. Cresteds her age don't eat much, so just put in a small amount of the CGD as suggested and you should be able to tell if she is eating it.
