Forgive me if this has been asked before..... I am in my second year of beekeeping, and this year, we had our first crop of honey! A couple of weeks ago, I extracted 2 supers, and returned both supers back to the hive that they came from with the intention of letting the bees clean them. My plan was to then remove one and leave the other with the bees for winter stores. However not realising that it should only have been on for a couple of days, i made a rookie mistake on the timings, and a week later returned to find that the bees were busily filling them both up again. I have heard that it's not wise to leave two supers on over the winter. I'm sure I'm not the only one to have done this, and I'd really appreciate some advice please on what the best thing to do is.
