Re: Moving a swarm
You can move them 4'-5' or so a day until they are where you want them to be
You can move them a couple miles for several days and them move them back
You can just move them the 30' at night and force them to re-orientate the next morning by placing some brush etc. over the entrance forcing them to re-orientate as things will be different to the foragers. I actually prefer to just place some boards stacked in front of the hive that forces them to come out and fly around the previous open entrance. Leave the boards there for awhile then you can remove them.
