Hello All It is a recommended practice to switch strong and weak hives especially early in the year to even up colonies, always carrying out disease checks beforehand of course. I need to switch hives shortly and it got me thinking (I know! thinking can be dangerous!). Now what is puzzling me is this. Bees do not like a queen which smells differently to what they have been used to - (hence the difficulty in introducing queens) - so why is the queen in each hive not attacked by the bees from the other hive?. Why do they not behave towards what they must see as a strange queen, as they would have behaved had she been introduced to them without protection?. The older flying bees are normally most of the problem during queen introduction. Could the fact that the flying bees do not attack the queen in this case be turned to good account?. To introduce a queen to each of two hives, why not switch the hives first?. Then all you would have to worry about are the relatively friendlier house bees. What do the list think?
