I installed my package of Italian honey bees into my TBH on Thursday (Three days ago). I am eagerly waiting my first inspection. I walked out today and watched them for a few minutes going about their business, they seem to be doing ok from the outside. I have been reading a lot about top bar management and came across an article touting the advantages of using spacers between honey comb because they said the honey comb is thicker than the brood comb. They claimed it is easier to assess cross combing with spacers. They also claim in the same article that cross combing can be caused by an electromagnet disturbance near the hive? Now short of putting a tin foil hat on every little bee head, I'm not sure what to do about that one. Interestingly the same people who wrote the article also sell spacers to go with the TBHs they sell. (Coincidence?) I'm taking all this with a grain of salt until I hear some other opinions. Thanks
