Report To Catch a Duck in Livestock Management Posted November 25, 2008 A sheep leg crook works wonders. Hook the duck's neck. I have a poorly designed duck tractor (that would be my own fault) and I catch ducks in it with my crook all the time. Never had one get hurt. I'd be tempted to keep it, too I love my ducks... although I do eat the extra males. I love my ducks, but I also LOVE duck!
