The proof is in the pudding.
Is your flock being preyed upon? If not, or if the losses are minimal, you shouldn't worry about it. If the occassional bird is lost to a predator, think of it as a tax.
If you are having constant losses then some engineering fixes can be applied. You will have to fence your flock in with a 6 ft or taller fence, and stretch wire across to discourage birds if pret from swooping in on them.
Think of it as a tax!! I like that!
