We'll after hearing for years from all the folks about queen excluders being hone reducers I wasn't in any rush to put them on when I reversed hive bodies last month and added supers. I sure am sorry now. On Sunday I checked my hives and I had some of the best Drone brood patterns I've ever seen. Frame after frame of solid capped drones. The queen after filling the lower boxes nicely with worker brood on Pierco foundation ran up two supers to lay in the top super (6 mediums up) where the natural cell comb was in some hives and where workers had built drone comb on worker size Pierco foundation in other hives. Ruined some nice Spring honey that they were bringing in from a the terrific early flow we are having in Upstate New York.
I spent a lot of time scraping drone brood down to bare foundation. I'm putting my queen excluders back on. I'd rather have a little less honey than nothing but drones. Drones don't sell as well as honey no matter how you bottle them :-). Sure learned my lesson.
