Hello all. I am up in CT and have been overwintering my hive with one deep (brood box) and two mediums that were nicely filled with a decent amount of stores. I've opened the top today to replenish a sugar brick and happened to notice that there were absolutely NO bees occupying the deep. The cluster is basically split up in both of the mediums. I took advantage of the warmer weather (bees were out flying today) and cleaned up the deep, being sure to keep the cluster grouped and closed up. I guess my question is, will they move back into the deep on their own when it warms up? Will they start trying to raise brood in my mediums? At what point can I pull off the mediums so they can build back up in the deep? Thanks in advance.
