My other post (Swarm entering hive) I told you guys about witnessing a swarm taking over a weak hive. Well that swarm has "left" that hive. I had 6 swarms and 5 hives. I checked in that hive yesterday and there were not very many bees in there so I know that is what happened. So why would a swarm enter a hive to take it over then leave it? I did see a little new queen in that hive yesterday and not a whole lot of capped brood. I figured she is just learning so I didn't see any new eggs, etc. When should I check on this hive again and would it be a good idea to put a frame of brood in there from one of my bigger hives - EVEN THOUGH - all of my hives swarmed - after I went ahead and split them? I don't want to reduce numbers in my good hives if I don't have to? I guess these swarms didn't want to be caught because everyone of them went to the TOP of an post-oak tree. The only swarm that was low enough for me to catch was the one that took over my weaker hive - then they apparently didn't like that home?? I can't figure these little gals out!
