I have only just put a wedge of wood in the door of my hive with a smaller opening in it for warmth and easier protection for the bees against robbers. I am confused about the core flute sheet I have in my flow hive which I moved from the bottom position to the top slot just before winter. The days here in Perth have been starting really cold but the days have been wonderful up to 23 degrees lately. So my question is - is all that ok or should I move the core flute down now its getting warmer or wait another few weeks for it to really warm up. And one more question - what is“a flow” when it comes to the bees foraging? How do you know when there is a “flow” and what does it look like?
