I have a raised coop (about 3.5 ft off the ground), and lock them inside at night. When I wasn't locking them in, I lost 2 birds in less than a week. A rifle also works great for 'yote control. I have Hogwire overtop of Chickenwire (as someone said, it's junk - it doesn't even keep my chickens in. I've watched my Leghorn chew right through it if she really wants out) and I am going to be replacing it with Stucco wire. There was a low spot in my current makeshift fence about 4 ft high - I watched a Coyote jump right over it with a chicken in it's mouth.. so build your fences high as they can jump!!
