I've been having predator issues lately. I'm sure of coons, for one, because of the carcass being left, minus the head & crop, but the other is leaving an exploded pile of feathers and no carcass at all. I'm leaning towards a fox or coyote for those, but hopefully its not an owl. These attacks seem to take place mostly in the mid to late afternoon. I really need the hens to spend the day out in my horse pens as their main purpose is fly control, but if they're getting picked off one by one every couple of days, it's hard to let them out. So, I'm thinking of running a hot wire above the top board on the fence. Hopefully it will keep these critters from climbing over (and keep the hens from going over too). Anyone have any pros or cons to this? What's the best wire set up to use? How far above the board should I set the wire? Thanks!
