The centre hole can be removed and a feeder placed over it. Alternatively, an eight way or rhombus style bee escape can be placed under the hole and used to clear supers. Heat from the hive will rise through the crown board vents, if opened. This can be used to heat a split brood box with 2 small nucleus colonies over the winter.
