I have a hive that simply will not produce any surplus honey. I started this hive last spring. The hive has requeened itself a couple times so that may have slowed them up some. The hive over wintered great and the box is full. I added a super on top of the hive bodies but after 4 weeks they have not drawn out any comb on the wax coated plastic foundations. The bees are up in the super but just seem to hang out there. Any idea about what's going on. Is there anything I can do to jumpstart them?
