Phil,
I move my bees twice a year. I staple a #8 wire cloth over the entrance, place a ratchet strap around each hive and cinch it up tight, load them on my home built bee trailer, I strap them down, back to back and hive to hive with ratchet straps and move them in the morning. Try not to do it during the middle of the day although it is probably cold enough that you do not have to worry about over heating as I we do here, right now.
Make sure they are not sliding around in what ever vehicle you use.
Jim
