I feed twice a day, putting only enough feed in the morning for the chickens to eat then around 4:30 enough for them to eat again before roosting. Hanging CDs to blow in the wind hasn't helped and DGibson said the owl with a moveable head wasn't a deterrent either. I bang on a water can any time I think about it and that scares up the flocks of starlings and sparrows temporarily. The starlings have figured out how to sneak into even the pens covered in 1 inch chicken wire. I'm thinking about getting some rubber snakes and strategically placing them. We are using rat shot in the 22 also.
What's rat shot? Besides fun to say.
