Re: My first Top Bar hive in North Pole Alaska! could use some advice.
Hey Chris, I finally found your thread with pics. Nice job. I was going to say that it looked like the feeder was a bit away from the cluster. When they get cold they can't move freely since they must cluster for warmth. It looked like the space was fairly large for their start. I would expect that you should move the slider up to make their space smaller in the beginning, to make it a smaller space to have to heat. I think somebody needs to come up with a bottle feeder design for a top bar hive, that allows the bottle to be in the space with the bees, so that it would be kept warm. Or perhaps a design that at least the syrup came into the heated chamber via a tube from the bottle, so that a portion of the syrup could be warmed by the bees. In either case, having the feed only an inch away from the clustering bees, would be ideal.
