I have found with the three deep system that the bees form a smoke stack
up the middle for the brood and put the honey on the sides so the brood
will go right up to the honey supers, and they won't get honey bound
usually. You also have to watch the bottom brood box as usually no brood
can be raised there as it is pollen bound, which works out wonderfully if
you want to make splits in the spring as the bees have plenty of pollen
below and honey above and no matter how bad the weather the bees are
booming in the spring and you can make early nucs. If you pull of the
bottom box and recondition and then put back on(same as reversing) make
sure and pulll out some of the frames of pollen and put in the top box so
they can keep raising the brood while the box is off.
