It is much better to give her fresh avocado. I wouldn't give her anything frozen. Just stick to fresh foods, which is what they find in nature. On a side note, always taste food to make sure it is good tasting before giving it to her. For instance, some avocados and apples look just fine, but really aren't tasty. Their sense of smell is far better than ours, so their sense taste is also more sensitive.
If you don't take her outside, open a window a little allow her to hear nature, assuming you aren't in a city. She ought to be acclimated to nature sooner or later.
