having browsed through the "Glenn Apiary" website I stumbled on the following snippet of information:
There is also a little picture of how that frame might look like. But the information is scarce.The bank frame has little doors for each of 55 queens. A metal bar securely locks the doors. The back of the frame is also covered with screen. After about a week when the queens are sexually mature, this frame will fit over a special box full of bees, which will feed the queens while they are outside the hive for the insemination process.
So, does anyone have more information on
1) that special frame (back and front) they used (design, thickness, etc.)?
2) the design of the box on which that frame "sits" (for/during the insemination process); e.g. what is the size of that box ... is it designed to hold frames ... special lid, etc.
I highly appreciate your help.
