Re: New Beekeeper. Single Brood Box or Double?
I would stay with the more traditional approach of double deep brood boxes and medium supers. Forego the queen excluder until next year. Add the second deep box and be sure to pull up two of the drawn brood frames and place them in the top box over the remaining brood frames still in the bottom. Fill in the open spaces on the sides of the broodnest with fresh frames. Do not add the supers until the second deep is mostly drawn out.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
