Two weeks ago tomorrow I performed a cut down split on my TBH. They have built out queen cells nicely. They have continued to be very active at the entrance. The queen should be out sometime soon, but I noticed an issue. They have filled the brood nest with nectar. I guess it's a good thing that they are bringing in so much nectar, but how do I go about this? Just leave them alone and let them figure it out or do I need to do something?
