Do predators have a time of day pattern? Or are chickens simply very attractive to the long list I am reading about? I have no dogs in my area. I am on 6 acres with lots of unoccupied mountain behind me. I do have a lot or Red Tail Hawks. I have never seen a raccoon but I am sure I have seen their prints in the mud. I suppose possums are everywhere but I never seen one around here either, not even as road kill. If I cover a large portion of the run with screen will the chickens know to run for cover or is any hole in the screen a sure invite to a meal? Thanks In Advance.
