Re: Running two queen colonies
Out of the 27 years of keeping bees there might of been 4 years where I didn't run double queens. For the most part I've usually had between 5 to 30 on the go. For me they produce much more honey the the regular single queen double broodnest hive.
Double queens are only a benifit to the operation thats running for honey production although I could see the benifits for bee breeders where a lot of bees are needed. The nice thing about double queen colonies is is that through the proper management, you'll be able to prevent swarming, produce almost twice the honey, and requeen. I don't think that running DQs are more work necessarily if you only need one to every 2 single queen double broodnest hives.
Where honey production is the goal, location and right timing for the different manipulations on those hives for those locations are crucial. For the most part, my hives are in double queen mode for no more 2 months max just to get the population up to where it needs to be for the main flow when it starts headed by the young queen i left with it from when I initiated the double queen.
The double queen system has a lot for it for the honey producer and not that it's a lot of work, it's just the timing is crucial for it to work smoothly.
