Most chickens don't like change and are scared of anything new. But eventually one will get brave and try it, then they all will. You'll notice that a lot of times with new treats. They are afraid of trying it, but when one finally builds up the courage and tries it, they all suddenly want their own.
You can carry them back and forth if you wish. I like the idea of tempting them with food, but after putting some food in it, I'd kick back and give them a while to figure it out, probably several days. Patience solves a lot of problems with chickens. And I'm not sure what your problem is anyway. Why are you in such a hurry that they need to get out there right now?
