Do the bees tend to fill the flow frames starting from the middle frame?
That is generally how the bees work frames from the middle out but not always, I have even found a frame capped on one side and the other side only nectar. For that reason always remove a frame and check both sides are at least 80% capped before extracting. What you see in the window is only of a novelty value. It’s heart breaking to have honey ferment – unless your into drinking mead.
Thanks Peter, that’s good to know.
