Thank you for your input. My primary goal is to NOT cause them to work their entire lives fixing a major mistake that I've made due to not asking the correct question! Your input/experience is greatly appreciated.I'm not sure it makes much difference as my bee's build brood on 1 1/4 & 1 1/2 inch bars. They put honey where they want to also. And they sometimes stick comb together at the top on the 1 1/2 inch bars.
