As a main mix that food should be sufficient to cover her basic nutritional needs. You can give her a few extras if you wish, but these should be offered as treats in moderation.
As the ham is technically still growing, you could give them a protein boost with a little scrambled egg on occasion, or some cooked plain chicken (these should be offered in portions no bigger than the size of your thumb nail. Anything they store will quickly spoil and them an upset stomach). You can also give a dog biscuit or a couple pieces of puppy kibble; these have plenty of protein, vitamins and minerals, though should be fed in moderation. High fat levels are essential to dogs for energy, absorption and skin/coat health, so kibble is very fatty and too much is not healthy for hams. Dried mealworms are also good.
You can also give a small amount of fresh fruit and veg, like broccoli, cauliflower, spinach, kale, apple, banana etc. But just as with the egg and chicken, only as much as they can eat in one sitting.
If you would like some help sexing, if you post a pic of the hammy's bottom we can help you identify.
