I have a question regarding pollen traps and collecting pollen. If we collect the pollen, aren't we taking their food? If using a pollen trap, do you leave it on or open or whatever all the time or at during certain periods. I was thinking about collecting pollen to feed the bees in the fall this year and maybe next spring in patties, but don't want to hurt any honey production this year either. a little help about pros and cons of pollen collection greatly appreciated.
