Two of my hives have been suffering heavily from Chalkbrood, so yesterday I used the Warré Pioneering method in an attempt to solve it. Essentially all comb and brood have been removed, making the bees start afresh, making new uninfected comb.
Both were established colonies in Langs, the bees shakend from the frames into the Warre funnel. This first is now in just 1 Warre box, and I am uncertain if the queen went in. With the second, a larger colony, I was able to find the queen on a frame and after getting her to climb onto a hive tool, was able to run her through the entrance, rather than risk the more violent introduction of shaking through the funnel. This latter colony had a good build up of stores, of which 3 half frames were removed for extraction giving a very light fragrant honey, much different to that extracted at the end of the year.
