A week ago we had a call out to retrieve a large prime swarm. We housed it in a six frame nuc, and closed the entrance disc so that the bees can come and go but the queen can't get out. It is is an out apiary. We fed after 3 days. However, it would appear that they are still trying to swarm every day, flying out of the nuc and then spending ages queueing up to get back into the nuc with the queen. Any suggestions on how to get them to settle and want to stay. I thought perhaps if we went along early in the morning and moved then into a full size hive and inserted a frame of uncapped brood from another colony they might decide to stay put. Obviously we would put a queen includer underneath the brood box until things had settled. Do you think this idea might work, and if not have you any other suggestions? Also what is the best way to keep a frame of open brood warm whilst transporting it from one aapairy site to anothert?
