A very easy thing to do! Was congratulating myself at the beginning of April on getting all colonies successfully through winter and were all strong and building up well. Decided to replace an old floor for a nice new one. Easy peasy, no risk involved, just lift the whole hive gently off old the one and over on to the new one alongside then slide it back into position, easy, whats to go wrong?! Next inspection no eggs and no queen. It took three attempts to get the colony re-queened. 'Killed a queen'? Yes a very easy thing to do!
What's the buzz?!
