I saw the post below this one and thought someone might have some input for me. I am wanting to have chickens again. I am in a much wilder area now. I have seen where a bobcat, I believe, dug a 5 foot trench next to a neighbors house that was over a foot deep and shredded the black plastic pipe that drains water from the foundation.I assume a wood rat ran into that pipe. While taking care of a neighbors chickens. I saw where a bear carried a 55 gal. barrel with close 50 lbs. of corn in it over 50 feet into the woods and ate its fill. That chicken run is chain link fence and there was no sign the bear tried to get to the chickens. I have seen a bear in the 400 lb range right next to my house. I have seen large mountain lion size tracks in my garden. I have had a coyote come on my porch and kill a pet cat, and hear them often close to my house. The place I want to keep chickens is not near my house and wondering what I need to do to keep the big guys away from my chickens. I wonder if welded wire fencing is strong enough.
