Hi Guys,

I'm just getting back into beekeeping after several years and I've recently read a lot about Checkerboarding and Opening the Broodnest to help prevent bees from wanting to swarm and to also help build up larger populations.
Has anyone done any tests or seen scientific studies with a number of hives that compare the two methods?

It would seem that Opening the Broodnest by inserting empty frames requires more bees to stay in the hive to maintain brood temperatures, due to the increase in the volume of the nest area. So may not be useful at lower temperatures.

So what about a combination of both? For example using Checkerboarding in early spring when temperatures are low and Opening the Broodnest in early Summer once temperatures are closer to brood temperature?
