Just bought a nucleus box from the excellent Modern Beekeeping in Devon for £29.
Admire the paint job! I like it. I wonder if the bees will. I bought a couple of sampler pots of "Shades" by Cuprinol, that were intended for the wooden bench that you see beneath the box. But looks good on the box, innit?
Unfortunately, it doesn't come with a central divider that enables one to keep two colonies in the same box. But a judicious hack at a sheet of Correx, the materiel du jour, fixed the problem.
See below with three brood frames in one side.
The final part of the job was to fashion a blocking panel for the entrance that will not be used if either the full six frames are being used as a colony or only one side is being used. See also the open mesh floor (essential for travelling any distance with bees on board).
I'm impressed with these hives. I have a colony in the full size polyhive and its doing well.
