The Beekers Handbook
I've done a lot of research (there can never be enough) and just added this book to my library.
I have to say that I am very impressed with the information here. It answers many questions that I've seen posted here recently.
Would like to know other's opinions.
One of my colonies is going gang busters, but drone and I were unable to see evidence of a viable queen in the other. Hopefully they use one of the queen cups to replace.
Using guardian entrances on the bottom board and a round one above the two brood boxes.
