After working our hives for the second year now I have some questions for the more experienced beekeepers in regards to the older frames that honey was extracted from. I have placed these back into the hives for the bees to clean up and use. Yesterday after pulling honey from one hive and replacing those frames with previously used ones I had the bees in that hive come out in mass and congregate on the exterior. It got me to wondering if it had anything to do with the replaced comb, so here goes. 1. We scratch the cappings off the honey when extracting instead of cutting. It leaves the comb ragged and uneven. Is this an issue for the bees to redraw it evenly? 2. If they even things out is it because they create more wax or do they chew/eat or consume wax to make it even? 3. Does it matter to the bees if the drawn comb is from different hives? I assume it shouldn't, because we mix them up and redistribute as needed. 4. Some comb appears to be very dark, almost chocolate in color. Clear honey has come out of these. Is this darkness due to the bees using that comb at one time for brood? Does the use of this comb in the super possibly confuse them or repel them in some way? 5. How long can the same comb be used repeatedly for honey production before needing to be replaced? Is there something to look for? Does it show some sort of wear or sign of age?
