There are many methods and options to raising queen bees, and this equipment allows flexibility to raise queens so any beekeeper can be successful. The ability to run this as a ten frame single deep colony sets it apart from most other options for queen rearing. Partitioning options are what probably most settled the discussion for me. I can drop in a five/four frame Nuc with a queen from excellent breeding stock on one side, open the bee doors to allow them to draw comb and store resources on the two four frame small partitions, and when ready remove the queen to a colony in need while allowing the newly queen less colony to start making queen cells. Distribute and separate all four partitions and you have up to four new queens, or up to four new starter colonies. Lots of steps in the middle, but the point is if you have another way, or idea, you can do you. The only thing I don’t like is the frames and joiners, but there are options to resolve that too (21stBee). Really pleased with this product!
