Just caught a swarm of wild honey bees. Put them in a 5 frame nuke box. When I first started bee keeping back in April I waited till 8 of the 10 frames where filled with come too put anuther box on. My questions are how to know when to up grade the new hive from the nuke box to the brood box? Do I need to feed the new hive this time of year? And when do I need to feed an existing hive?
