Hi Philip,
I was taught to never harvest from new hives and to me it makes a lot of sense. I run 3 mediums for them, but sometimes cut back to 2 right before it gets really cold and freeze their used brood frames so i can add them back when it gets warmer.
If they start pushing the limits the first year , I'll give them another box above a queen excluder but I always make sure they have at least 6 frames of honey and pollen above the brood..
