I started with a strong hive this Fall. (Carniolins) I fed three global patties this Winter and in February (15th) I reversed brood boxes on a mild weekend. My deep was empty and I moved it up above the brood and queen. This past Friday the 6th, bees were really booming. I had the deep full of mostly capped as well as open brood. I found the queen and marked her. I again reversed the boxes to keep the queen moving up. I started feeding and added another mid super to hopefully draw some more comb.(short on drawn comb) I have queens coming in May and I'm afraid if I can't manipulate the frames enough, they will surely swarm. I plan on splitting, but queens are coming late I think to beat a possible swarm. Should I go ahead and find the old queen and make the split? Should I wait for swarm cells to appear? The hive is really strong. (deep, medium and shallow and now medium foundation for them to draw comb.) All the boxes are full of bees. Temps have been in 70's this week but falling to the 50's by this weekend. Have I rushed them too much? Swarm season may start in April here. I'm on the Cumerland Plateau near Jamestown, TN.
If they have filled most of the 2 boxes you have on them do the following:
1. Add a third super, make it a deep so you can utilize for the upcoming split.
2. In each of the 2 cureent boxes pull the 2 outer (storage) frames from each box (4 total).
3. Move the remaining frames so that there is a free space between the last 2 brood frames on each side of the brood box.
4. Insert the empty frames from the new super into the empty spaces.
5. Move the 4 storage frames up into the top super so it has 2 empty frames, 2 storage frames, 2 empty frames, 2 storage frames, and 2 empty frames.
The reasoning is this: bees building in the brood chamber usually don't swarm unless they're crowded and you've just removed that problem by supering.
The super is baited with full or partial frames from below to help draw the bees up into the super.
This will delay a swarming tendency for about 30 days, which is what you want, and you'll have the plus of 3 boxes of bees from which to do one Strong or more normal sized splits.
