How long does it take for a hive to reflect the genetics of a new queen? In looking through past threads, someone mentioned a hive can change temperament in as quickly as "2 brood cycles". Does that mean 42 days? He was commenting (I think...) on someone not paying attention for a period of time and finding their hive had gone from gentle to unruly. But, would this hold true for requeening the hive as well? One could expect 42 days of the old attitude before it changes to a new? And, to build on that, if one takes a swarm, let's it operate with it's swarm queen for "one brood cycle" (21 days) then requeens it, would the attitude of the first queen's offspring be enough to change the swarm's original temperament or by there only being one brood cycle (if I'm understanding that term correctly) would the changes be minor and of shorter duration before the second queen's offspring replaced all? And am I so confused I can't even ask the questions in a coherent manner?
