Re: 5 Foot Queen Castle
I have 3 four compartment castles setting side by side on a stand. basically creates exactly what you have here. alternating top and bottom entrances as well at front and back. I found I had problems with the bees trying to return through the vents. I cut them both front and back on my first one. the other I cut the vents in the bottom. I also need to make my entrances large. I drilled mine 1/2 inch and now think they should be 3/4" min and possibly 1". I just put 12 queens in the entire thing in the last couple of days so I still have to see how well they return to the correct compartment.
One thing I notice about your color selection. I looked up how bees see color the other day. I can't remember all the combinations but I do remember that they see white as blue. They also see red as black. From what I can tell bees will see different colors in your scheme except where you have a red and black compartment next to each other. It will be interesting to see if you have any particular problem with those two.
Keep in mind that from left to right bees are going to see. Blue, yellow, blue, Black yellow, blue, black blue, etc.
