Brood Chamber for British Standard National Bee Hive

?Also known as a brood box, this is the box that the bees raise their young in. It is called a brood chamber or brood box for this reason. It is properly known as the ‘British Standard Deep Box’.

It is also called a ‘deep’ or ‘deep box’ and confusingly it can be known as a ‘deep super’ if it is used for honey gathering.

Use for raising brood is most prevalent. However in USA it is common for all boxes to be ‘deeps’ for interchangeability. In UK we adopt shallow boxes for honey and deep ones for brood to avoid breeding occurring in frames that are to be extracted from.

The top and bottom rails are identical to those used for making supers and 14″ x 12″ ‘extra deep’ brood boxes.

The ‘Standard’ calls for bottom bee space, but some in UK have adopted top bee space. Such top bee space items are dealt with on the “Rational” group of pages.
