First I'll start with saying thank you for thinking ahead!
- wire: chicken wire keeps chickens in, but does NOT keep predators out- use welded wire- also, if possible, either bury the wire 1-2', or bend 1' OUTward so that predators can't dig under.
-coop doors: coons learn to use latches...If you have the option, make your people door the same as a house door with a door knob that's lockable. One way to keep coons from learning to open the pop hole (hen door) is to latch it from the inside! Otherwise, you can always lock that one too.
- if you have the funds...I recommend an electric fence around your run/coop
-Many folks extend the wire over the run...to keep climbers out (like coons)
good luck
