Bee Swarm #2 in My Fence

I’m a one beehive kind of guy. About two weeks ago I saw evidence my hive was splitting–a second queen was on the scene (only one queen per hive).  The breakaway hive was inside a  double-walled fence about five feet from the original hive. Before I pried the boards to see what was up, I took a photo of two zombie-like bees emerging from the fence. (see below). When I took off the boards, I was “shocked” by the size of the swarm and the large number of honeycombs.  I called for reinforcements and last night after two hours we were able to put the fence bees into a safe hive. We used a smoker to calm the bees, then gently brushed them off the combs into shoe boxes and from there, into a “brood” with waxed frames. Lots of bees that didn’t make it into the brood congregated outside, signaling to us that we had the queen in one of those swipes. We taped the entrance shut and left the hive overnight to allow the bees to calm down and gather around the queen for protection purposes.This is the second swarm in the fence in the past 18 months, so I will put up loose boards in anticipation of a repeat.
