Regarding predation, EVERYTHING thinks of Duck as a gourmet delicacy. Predators you didn't even know were around will come out of hiding to hunt your ducks. 10x worse than chicken predation. I had Welsh Harlequins and Cayugas, a mixed flock of about 20 birds to start. Even with electric bird fencing surrounding my chainlink run and secure coop and a bird netting top, I still lost every single duck within 2 years.
