Have you tried feeding them when it is time to be locked up, at the place where you want them to be? Doesn't need to be a lot of food, just something they like, to get their attention and start building a habit.
As far as what to close them up in, really anything big enough and predator-proof will do; if you don't want to build from scratch, something like a doghouse with a door/vents added, or a wooden shipping crate, etc...
