Here's a question. I want to raise queens in the near future and I've been reading the books and trying to derive a workable system. Would it be possible to make a "communal" mating colony. I'd split the bottom super into 4 2-frame compartments (like Brushy's Queen Castle) than put a queen excluder on top of the box, and another "food" super on top of that. The bees share the top super, and the queens hatch below, mate, return, and I have a 4-queen colony. After each queen lays in her 2 frames I take out the queens, introduce new cells, and the process starts over again.
Really the only question I have its, will the workers accept only one of the queens and kill the others, or can I build off of the principles behind running a 2-queen colony?
