Our hive swarmed last week but we were unable to capture the swarm. For the last few days the bees have been gathering in large clumps all over the front of the hive and are pretty durn grouchy. They stay in these clumps all night and in bad weather and have chased me away on a couple of occasions. Before they swarmed they were fairly docile and friendly. We're curious if this is normal behavior post-swarm. If they stay this grumpy I'll have to re-queen. Thoughts?
