Over the past year have lost 5 of my hens to hawks, well maybe one to something else but pretty sure the bulk is the hawks. Have seen threads on hanging cd's, owls, dogs, a ton of stuff. my situation is I have a 14x14 coup, and 14x18 wired and covered run. This is at my shop and i am not there all the time. I let them out to free range in the morning on my way to work and put them in at night (shop is not where I do my real job). Since i am not there most of the time getting a larger animal like a dog to watch over them is not an option. So how does the hanging of cd's work? Should i get some owls (plastic),roosters? or any other thoughts? the property is 3 acres and mostly open surrounded by woods and the ladies like to run all over the place. What to do other than accept this as a fact of life or????? Thanks!
