It is important to look once a week , what is happening in the hive. It is learning. If you feel that you must se more, so you look in.
You will see, that first bee draw upp combs. Queen lay eggs. Soon limits are met and nothing happens. Just wait. After 3 weeks new bees begin to emerge and one hive can enlarge it's brood area. Hive bees take thier place an d old ones gathet pollen and honey.
What is important so see in little hive that there is free combs to queen lay eggs. If not, it will swarm. If hive is full, you must take fod frames away and you give foundations to build.
When one box is full of bees you put second box lowest and bees can enlarge there. An so on.
