What are your best tips for making a coop/run predator proof. We plan on getting chickens in the next two years and are doing our research. I live in Montana. The area we live in has bears, mountain lion, coyote, foxes, hawks, and your run of the mill ground rodents. I am thinking I will need the run enclosed both on top and bottom (how do I do the bottom?) I know it's not good for the bottom of their cage to be wire, do I bury it? Also, I don't think chicken wire will keep out mountain lions. Do I double fence it? Any plans or suggestions are greatly appreciated.
