You might also buy a few air horns, They run about $13 and are available where there are boating supplies. They are air cans with a horn on top with a button you depress, really really loud. Canines hate them. We have problems with owls, eagles and hawks so have hung long strips of that bright orange snow fence between trees in flight patterns about 6' off the ground. Altho we have not lost any (yet) our neighbor up the road has lost two full grown hens to Great Gray Owls.
