Re: Top entrance?
I am moving away from the SBB's. I think in a cold winter they are detrimental to the colony. I also run top entrances, but have had problems with the bees staying high in the hive and not filling in the bottom deep. I am thinking of using a side (front) entrance in the bottom deep to encourage them to brood in the bottom deep. Bottom entrances are not an option with the skunk population.
