This is a common occurrence to have your brood chamber become honey bound during the main nectar flow. A typical hive body will have a brood cluster in the middle and the outside frames will contain honey. A honey bound hive happens when brood begins to emerge, it is replaced with nectar.

In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
