If you have problems with naughty kids, a sturdy pen with padlocks are the way to go. Use strong hardware cloth wire, and bolt it down with screws and washers. My pen has 4 x 4's at the corners and 2 x 4 framing along the top and bottom. 12 inches of hardware cloth is buried and aproned out along the bottom. The top of the run is covered with corrugated metal sheeting. It is predator resistant, and long lasting. The henhouse yard is one of the coolest places on our property in summer. Make sure the door and door fram is well contsrtucted to keep people from easily breaking in. I use chains and padlocks on mine when I am not around. Also, i have a "driveway alarm" set up where people walk to the pens. Inside the house is a reciever that chimes anytime a person walks past the device. Mine cost under $30 and has a decent range. I really recommend it.
