I opened up one of my hives today to get some frames of brrod and honey to set up a nuc for a queen I purchased. I had around four frames of small cell foundation in the second hive body to see what they would do with it. They did not draw out the small cell but had placed a bunch of burr comb on the foundation and it had such depth that it was actually pushing the foundation out to one side. I took all but one frame of the small cell out. The frame I left had a good amount of brood. How best would it be to introduce small cell to the bees?
