I compared the weather in Butler to here and they are almost identical. Geography I'm east and slightly north but closer to the coast. Anyway, yes, I have added a foundation filled super to each of my colonies. I'm only feeding the weakest one. I wanted to make sure that I wasn't going to force swarming before I continued. I'd rather do nothing than cause that.
Right now I have a three stack, two deeps and one medium. The deeps are 16 frames pretty well covered with bees. I'm not sure exactly how much brood because I don't want to slow them down by disturbing them with an inspection. When I rotated the brood boxes late in February I found that the population was full in both boxes. Drones were already abundant, drone comb had webbed the frames together. I think that the only thing that has been holding them back is the low temps.
This is why I've been asking all these questions. I've done my homework but I'm on unfamiliar ground. Nothing takes the place of experience.
That's where you guys come in.
