Four new hives, started last Sunday, have very little activity, are eating from a top super feeder and don't show any capped anything or larvae on the frames. I'm very worried the week long rain and chilly weather (high50s), which is expected to continue, is keeping the bees in their hives and not collecting any nectar/pollen. Would a pollen substitute make the difference? Could it be all 4 queens didn't make it?
