One thing I experienced, and I don't know if it is typical or not, but just in case....
I started with 1 medium of brood and 1 deep of brood.
I put in a frame of capped brood. It turns out that the either it wasn't centered well, or there wasn't enough space between the glass, and the emerging brood had trouble getting out, and a whole bunch of brood died. I ended up taking out that frame and letting them draw their own.
My observation hive overwintered with about 6 lbs of honey and less than one medium frame of bees, and they are still going, so small doesn't matter too much unless they have more room than they can defend.
If you want to watch them build comb then I'd do 1 frame of brood with eggs /w bees, one of capped brood with pollen w/bees, shake 1 or 2 frames in, and then feed them. I think your hive is bigger than mine (I have 2 deep + 1 med frames) so you may want to add more.
I love watching them build comb...
