This morning my wife looked at the window and saw the chickens running onto the back porch. Further down the yard a cat was slinking along the ground. It appeared to be stalking them. I'm an animal lover, but the cat didn't belong to me and I like my chickens a lot. I ran out to the backyard and threw and apple at it, then the dogs chased it over the fence. I guess i'm going to need to put some harware cloth and my new tractor instead of just chicken wire. Would a cat attack a 12 week old hen? Or was it just messing around, like when a cat stalks a shoe string.
