Over the years I have had the worst luck with predators getting into my coop and nabbing all my chickens. So now I'm building a chicken run and coop closer to the house just so I can hear if anything is happening. It seems in other designs I have tried everything to keep the girls safe and well but just this week a bobcat dug under the wire of the coop and got into the coop and killed them. We also have lots of trouble with raccoons getting in the coop from above even with the wire overhead. So with all this in mind, anyone have any ideas of a coop and run design that is practically impenetrable? Pics could be helpful too! Thanks!
