You should extract the capped honey. Medium box has 15 kg capped honey.
Bees cather more when they get empty combs.
4 boxes = 60 kg.
If you do not extract, bees swarm. If you take capped honey to storeroom, it crystallisez and you cant do nothing with honey.
Keep hurry to give new room to nectar! Foundations, new boxes, extracting..
