Looking for advice here.

I have 2 hives about an hour from home, one of which is exploding like crazy.

I also have a small swarm that moved into an empty hive at home. Probably only a fistful or 2 of bees which are being fed.

If i want to move a frame of brood from the large hive an hour away, what is the best way? Do i just pop a frame in a brood box with floor and travel screen and transport them? Or is the lack of heat going to cause issues?
