I have a hive that is well not acting well the bees are there but sluggish can open hive use no smoke while doing inspections, the brood patteren is all over the place. The color of some of the bees are very light not white but very blond they fly to and from hive bringing in pollen. I guess am asking is there a hive maintenance med. that can be used? Or could this be just a bad queen or no queen?
