The above suggestions are good (treats, chickens, habit), and we also brooded our original hatchery keets in the outdoor coop (with heat lamp, etc) from day 1, so it is the only home they've ever known, and they teach new ones where to go.
Ours do coop at night but you need to be prepared for more work than with chickens, who will go to bed on their own. DH goes out each night to encourage them in and if he did not, only some would choose to coop. We don't use the night treats method though. If we did that might speed things up but I think DH kind of likes standing out there talking to them & poking them down out of trees if necessary.
My bottom line opinion (worth what you paid for it): Get chickens first if you've never had a flock. Guineas would have been too much for us if we hadn't learned to deal with chickens the year before.
