So, here's the situation. It is my 2nd year beekeeping. I was wanting to experiment with single deep brood chambers. So I went to the yard over the weekend and tried to use one of my double hives that didn't have anything in the bottom box. However, when I got there there was 2 frames of brood in the bottom box. So, instead of putting them into a nuc and creating a new colony I made a rookie mistake (Hindsight is 20/20). I reversed the boxes so the full box was on bottom and the few frames of brood was on top with a queen excluder between the two to keep the queen in the bottom box. My thinking was when the brood hatches out I can just remove the top box. Now, I realize that it probably wasn't the best option. So should I remove the exluder and wait for them to build up to 2 full deeps and do a split? Or should I do a split now and put them into a nuc? Thanks for the replies, sorry for the novel that I wrote.
