to Really Get Going

This small hive is called a nucleus.  It is half the size of the honey producing colonies on either side of it.

As you can see it is overflowing with bees.

Bee-keepers will keep a nucleus to act as a reserve if any particular colony should lose a queen.  It does not in itself produce honey for the bee-keeper.

I use this nucleus, by removing an occasional frame of brood to put in a hive that is not quite strong enough.
