Good luck!! I got a fake owl for my yard. I put it on top of one of the bantam coops, so it wouldn't scare the chickens, but the hawks could see it easily. I got the one that is motion activated, it turns it's head and hoots...totally unnecessary. Just get a cheap one. The batteries have been dead for a year...lol Haven't lost a bird to a hawk since I got it though...knock on wood!!
Do you think this will work for me? I just had a hawk attack the other day (thankfully no fatalities!) but I need to build the defenses!
