I am thinking about slipping in some hard sugar candy, perhaps later in February. I've never tried the candy before. Some suggest just putting in some sugar on top of paper on the top of the hive frames, but I might try the candy this year. Last year, I put on sugar water feeders in the spring and the bees really never consumed any of it. They still had a generous supply of honey left in the hive, and hopefully this year will be the same. Can't help but worry, though.
