i'm thinking of using them next year, and talked to a friend and mentor on how to make them.
Anyhow, in our dicussion we were talking about the reason for making them a certain way
...to prevent drone brood from being laid on the bottom of the frames due to to much space between the brood box and the screen
...Wax moths getting in the tray of the SBB and having a hayday cause of all the garbage that fell through the screen
In thinking on wether or not to build these things, I had a thought.
One of the atributes of a good queen is the ability to keep her hive clean. But with a screen bottom board we are taking that away from her. I mean now the bees do not have to clean the bottom of the hive, we do it.
When i look in my hives i am constantly amazed that the real healthy hives are the ones with a real clean bottom board. Are we going to end up breeding that out of them if we always clean the tray in the SBB? Are we going to end up breeding out a job that they do, and make the beekeeper do it? I see alot of talk about genetics when it comes to queens and healthy hives. Is not a queen keeping her hive clean part of those genetics?
just a thought.
