i heard growling in a hive yesterday took it apart but there were no drones in the hive but could not find what it was as it stopped as i moved the third frame from the end
just wondering, how strange that you ask that question for the time you have been keeping bees, the notes from other years that you talk about and the advice you give to others i would of thought that you would of known the answer to that question from your past experience that you say you have ??
