Welcome, and DO like tamlynn says.

While chickens do tend to get a bum rap, it is also true that they are not on the same page as we. Creatures of habit, they don't always take well to being uprooted and you can't just lay out a red carpet for them and have it mean anything.
What you consider a dandy home for them may not strike their fancy, initially. So, just turning them loose and then expecting them to come trooping merrily back may leave you hanging.
The solution is to keep them "cooped up" for a few days (thus the meaning of the term) in and/or around the coop. Also, feed and water them in there to start with, say for a week or so, until they grow accustomed to the new digs.
After that, start expanding their horizons and giving them more allowance. Eventually, move their feed and water outside the coop, protecting it from the elements. By then, they'll know where home is.
Oh, and lets hope you have a handle on predator control, now that you've moved a chicken buffet into the local habitat. Assume nothing; you may want to hang out on the predator forum for awhile.
