Over the winter I built myself a top-bar hive, which is now ready for use. I could populate it with a split from one of my Langstroth hives, but that would be work, and I like to have the bees do the work. So I thought I'd leave the new TBH out as a swarm trap and see what happens.
My question: Should I leave some of the top bars off, to create a bigger opening and make it more attractive to a swarm?
