Came home today to a swarm ball in a limb beside my hive, I finally managed to get it into my extra 10 frame hive I had on hand at about 6pm. Temps are currently 55 with a low in lower 40s predicted. I stuck the entrance reducer on to help hold in more heat. Its setting beside my other hive. I have to go to work early in the morning so want be able to do much to them except maybe move hive if I need to. I'm wondering what's my chances of them staying?
