Today I went out and added feed to the last two of my hives. Its now the January thaw. In these two hives the cluster in Hive J was at the top. In Hive N the bees were still 2 to 3 inches below the top. Both hives appeared to have adequate capped honey still available. But to both hives I added a sugar block and a portion of a winter patty to insure against starvation later in the winter. I will probably be checking all hives again in mid February. At this point 85% of the hives are still humming in the apiary.
Spacer gets sealed with duck tape since bees won't be able to propolize the crack.
