I had a male and female pair of Ruien ducks that were never more than 3 feet apart , ever. they just turned 11 months old and we were looking forward to eggs in the next few weeks. I see the drake in the duck house, alone and I already knew she was gone. Found her in the wetland/ drainage ditch still in the water with her neck eaten to the bone. Lots of cover (cattails, willows, etc. ) be hawk got in there through the narrow opening. That's the 3rd bird in a year lost to hawks. I have a good dog and a rooster, but short of penning them up all day what are some option to deter hawk attacks ? The crow decoys didn't help. -Thanks
