Transport of adult birds is often best managed using wire dog crates if available, if not then you will need several large cardboard boxes with air holes. Keep them in the temperature-controlled vehicle if at all possible - I know lots of people transport chickens in the back of a pickup, and they survive, but sun can make them very hot quickly even if it isn't that hot out yet, so if that's your only option you will want to have a tarp for shade and to block as much wind as possible. You will have best luck if you keep them confined to the coop and run for at least a few days until they know where they live, and until they are reliably going into the coop at sundown; then the first time you let them out make it about 30 minutes before dusk so they won't go very far because they will know it's almost time for bed. Gradually let them out a bit earlier until you know they will return. While they are in the run, go visit them with something they think is fabulous - most will come running for meal worms - daily or twice a day. We have birds that are let out in shifts, and they know they are getting a snack every afternoon around 2 or 3, so the morning rangers come running into their run at snack time, and once snacks have been consumed the next group is let out - this group consists of only a couple of the old ladies, and once they've dust bathed in favored spots and checked for bugs and other goodies in a few locations around the property, they head back to their area and I put up an ex-pen to confine them to a smaller area and let out the third group for the last 3-ish hours of the day. All this is to say, they will learn routines, you just have to decide what the schedule is, then try to stay with it as much as possible.
