Lizzie, your bees are doing what they should be doing, drawing foundation out into comb and storing nectar. With a new colony the first goal is to have all frames of foundation drawn into comb, especially in the brood nest, then the surplus honey supers.
Bees are slow to work the outside frames when drawing comb. The beekeeper must move drawn comb to the outside and place the undrawn foundation toward the middle, usually between frames of sealed brood or sealed honey. This aids in having the comb drawn to a uniform depth. Bees draw the foundation best when either between brood, or just above brood in an upper box.
If you have 8 frames of brood, your 2 deep colony will be overflowing with bees when the young bees emerge. If you don't have surplus honey supers now, you should get 2 so you can put them on when needed.
