This is my first year of beekeeping and my first winter. We had some abnormally cold weather and snow during January and I hadn't seen any bees flying in a couple of weeks even though there was some warm days in between the cold snaps. When I looked through the viewing window all I could see were a few dead bees and no live ones. Decided I might as well harvest the honey that was left so I started taking out the bars. I went all the way through the hive and pulled each bar out looking for bees. I only saw a couple of live ones while doing that. There was one cross combed bar that I left together until I'd gone all the way through. When I went back and broke it apart there was a small ball of bees in a cavity between the two combs. Fortunately, the comb didn't break off so I put it back together and put the bars back leaving them some honey. I doubt they make it until spring but I have my fingers crossed. Almost all the bars in front of the huddled mass of bees (toward the entrance) looked like this one. Is this normal for mid-winter?
