ok so our coop is coming along, and now we have to start thinking about the run! we're trying not to use treated wood, because of the potential crap that can leach into the ground , we know the drawbacks, anyway... does anyone have any suggestions for how to secure the run to the ground so that other critters can't get in/under? i've read about burying the wire i'm just very simple-minded when it comes to all this building stuff , so how does one bury the wire? do you have do dig a trench ?? help please! we gotta get the chickens out of the house!!
