I've been hearing an owl for about a week in my backyard right before dark. I chose to start locking my chickens in the coop at night rather than leaving it open to the pen like I have been doing. The other day, I opened the back door and the owl went flying away from the coop. I bet it was just about to make a move! The next morning, my roosters were crowing as usual, and then I heard the owl hooting. The roosters stopped crowing all at once and I never heard a peep out of them the rest of the morning. I put a scarecrow near the coop, hoping that works to scare away the owl. Are there any other practices to scare them away and keep them out of my yard away from my chickens?
