The bees in our top bars are working hard and fast. One is building comb on 10 bars already. At this rate they might fill all the bars this season. This is the first year so our plan was just leave them alone and build up a reserve to limit the need for feeding. Is it wise to split a hive late in the season? We’re having issues with a longstroth and preventing it swarming. We might have to split it but it will be soon so they can get established.
