We have decided that we definitely want a hot wire around the outside of our coop and run because of coyotes, possums, our dogs, etc. But I don't know anything about running these wires. What do you do about the door in the run? Do you just have a door that opens to the inside, then step over the wire? If you run the wire up and over the door, then that section is unprotected, and that doesn't sound good to me.
