There is a family of barred owls living in my backyard. I've tried to get pics but they never sit long enough. I've seen the parent with 2 young and watched as they hunted birds. They remind me of velocioraptors! On the game cam, there's lots of white squiggly lines which I think are the owls flying through the cam's field of view. Here is one pic of something! I don't want to kill the owls but I worry about my chickens and the koi in my pond. The owls come out every evening just before dark, about a half hour before the chickens go into the coop. My pen is covered and double-fenced so they can't get their talons through. Any ides how to scare owls away?
