Ok in my TopBarHives I have been noticing a trend. When the has gone through a cycle, the bees are starting to use the empty cells for honey instead of more brood. The brood nest is shrinking and becoming some snake like thing twisting through the hive. I have started putting in empty bars in the center of the brood nest to open it up a little and give the queen some fresh combs to lay in.
I was wondering what your opinions of this brood nest shirkage is. The brood nest is about 7 - 1.25" top bars, and the brood usage is being shrunk to about 1/4 - 1/3 of each comb. The first 3 or 4 combs in the hive are still 75% brood comb, but this doesn't seem like much. This is the area I stuck 2 emtpy bars.
