I also have a TBH that is 36" long, 14" wide at top, 9" wide at bottom, and about 10" tall.
I was gone for a two week vacation, and when returned, all of the bars had comb on them. It looks like 10-14 bars are brood (I have two hives), and the rest 8-10 are honey/brood/pollen. I think the last few comb are only honey.
I also am seeing some queen cells.
So, yesterday, I made the same dimension hives, but 48" long instead. Tonight I plan on transferring the top bars with comb to the new hives. Hopefully that will stop the swarm attitude (I'll cut out the queen cells) and start more honey production.
