I have a 5 foot KTBH and they currently have 4 feet of it. I have about 9 bars of brood comb and maybe 3 bars of syrup plus 15 or so empty bars. I think I fed them too long and they began to fill the brood nest with syrup then built two queen cups and sealed them. About a week later the queen cells had holes in the side and they cleaned out the cells (i still have a laying queen). Well I took away the syrup but now they have built 4 more queen cups but have not yet sealed them, I'm not sure if they have eggs in them or not until I can do a full inspection. It also seems the population has exploded with bees coating the inside of the hive walls and floor, maybe due to recent high temps in the mid 90's. I'm assuming they are going to swarm once the queen cells are sealed. I check it everyday through the window, what is the average time the queen cells are sealed before they swarm? Just wondering when I should make the split once I see the cells capped.
