I am not very sure about the budgie mix that you posted the link for, but I worry about the fruit in it as I could not find anything showing me a good look at the fruit or telling me anything about the drying process. There are additive that are used to preserve the appearance of the fruit and if the manufacturer bought the fruit to add to the mix then they do not have to list these additives or admit that they are present.
You really have not said very much about your new friend so I am not sure what to say other than it sounds to me that you are really trying to provide what you feel is best for her. I would love to see a picture or two or three of her. What color is she? is she an American budgie or an English budgie? It seems strange to me to use American or English in regards to them as they hail from Australia in the first place.
