When the hive is managed without [[queen excluder]], the queen lays eggs into a wide area. If there is no nectar flow, the eggs can be found everywhere and there will be no brood in the lowest hive body. The queen should be kept in the lower boxes, as the Nordic brown bee is not suited for “queen in upper box” management where the queen is closed into the uppermost hive body with a queen excluder.
After the number of worker bees increases rapidly in June, the queen will be even harder to find. That's why it’s best to complete the procedures that will help in finding the queen (for instance, marking the queen) in spring, early summer, or late summer.
With ''A. m. mellifera'' bees, it can be difficult to establish two-queen bee hives with a separating queen excluder. Usually, the other queen is killed and only one queen is accepted per colony. Then again, this behavior can also be an advantage when the old queens are changed to new ones.

* Work with care and keep in mind that some of the queens can hide outstandingly well.
* The queen usually goes to the empty built frames, which have been recently given to the hive and are also occupied by worker bees.
