Top Bars getting double combs
I tried to standardize on one size of top bar for 3 of my tbhs. However, after seeing some of the bars getting two combs built on them, I adjusted the brood bars to 1 1/4 for my 4th hive. This adjustment is working out fine for that hive.
However, I have 3 hives that have built 2 combs on 1 bar. These are brood combs which I plan on moving out from the brood are into the honey area in order to move in smaller bars. What other options do I have with this double comb building? This problem is my fault for trying to use a on size fits all top bar width.
