As Iddee knows, I have robber screens on my hives to keep them calm despite the chickens fluttering about in the same pen. The bees are doing well and are really happy. Their hives reek of goldenrod so I know their food supply is good. The plan is to put the sticky boards on again on Thursday (second mite count of the year). My bee school students will be coming to my beeyard next Saturday after class to learn how to check hives in preparation for the winter and at that time, we will check for stores, disease, pests and queenrightness--that's whent he boards will come out. But I got to thinking. . .if I have robber screens on, are the bees still able to evict the drones? I think I've had them on year after year and all went well, but now I'm wondering. So I took the robber screens off this morning but I'm anxious for the chickens. Love to get your thoughts on this.
