Apparently we have a bobcat in our area. We are already designing our coop to be raccoon and coyote proof (I hope) with only one entrance door to the run (with two locks) that is human height. The hen house clean out door and egg box door will be inside the coop and also lockable. We are using hardware cloth along the sides and a galvanized metal roof on top. I will also be adding a 2-3' 2"x4" wire fencing apron around the base and at least two sides will have gravel or logs on top to keep erosion down. Any other suggestions/advice? I read that bobcats are most active three hours before sunset and three hours after sunrise (plus after dark and before sunrise). Is that your experience with them? I guess my chickens won't be free ranging during that time! Thanks in advance!
