Commercial Beekeepers do not have the TIME fool with or maintainence two-queen hives.
Can you elaborate on that please. What I am seeing of a two queen hive (tower) is it is actually two separate hives with one common section that are all supers. If something is common than that should mean there is less equipment involved. I am obviously missing something here.
You need to go to work for a Commercial Beekeeper some one like Merrimack Vallry Apiaries who has about 12,000 hives then you can tell me about time.
