I have both flying and non-flying duck breeds that free range on a daily basis. We have 5 acres that we divided up into 1 acre fenced in sections with no climb livestock fencing and then ran two lines of electric on the outside to deter ground predators (one at the top and one at the bottom). Now my duck coop has a 12x12 run attached that is roofed in, has hardware cloth on the sides and the coop/run is in a 20x20 fenced in area. Then the whole 20x20 fenced area/coop/run is in one of the fenced in 1 acre pastures that has the electric on the outside. There are 3-4 trees and several bushes for protection from arial predators in the 1 acre fenced area that my coop is in and at night I lock everyone up into the coop/run. My ducks are out ranging from 8am-7pm (or whenever it starts to get dark). We have never had any issues free ranging, but our neighbors right next to us who also free range their ducks (they only have trees for protection with no fence/coop) have had several flocks picked off by foxes, racoons and coyotes. In fact the neighbors came over yesterday to look at our set-up because their last couple ducks were recently found dead. I know that I'm a bit paranoid and my Ft. Knox approach may be a bit excessive, but I absolutely adore my ducks. So in the end it really depends on where you live, what precautions you implement and what risks you're willing to take.
