I am looking out my window at my hive, lots of activity, it looks like new hatch is coming out today. I have had one hive for about 10 years, with varied success. The first hive I made in an egg shape, from cow dung, clay and oat straw. The bees loved it, thrived in it, but I couldn't get very far into it, the frames never came in and out well enough. (I'll dig up a photo and post it soon) When that finally fell apart I replaced it with a Langstrop, and the bees have been less healthy since then, so perhaps this is a clue to bee health? This year I fed and treated diligently, isulated the hive during the coldest stretch of winter, and actually put a low energy lightbulb beneath the hive for a touch of warmth. So far, so good. This is the first winter I have had a hive survive in about 3 years, so I am happy, but still apprehensive that they will all vanish without a clue one day.
I'm wondering about other backyard, non-migrant small keepers survival rates. The bulk of the collapse seems to be migrant bees, I think, is that not so?
