I had 2 ducks one pekin male and one rouen mix female, first the pekin was gone we found only a few down feathers on the side of the house some with a little blood now my female is gone with no trace of any thing. I live in a suburban neighborhood but on a shared acre(duplex) and all the houses around are on an acre. We have woods in the back, for about 50 or so feet and a housing development on the other side. We frequently have deer in the backyard and I know there are raccoons. I did see 3 hawks which came so low I actually sprayed them with the hose, they were being chased by crows scared the crap out of me! The neighbors feed stray cats so there are always cats around. My son looking in the woods for Lucky the pekin came across a pile of "big" poop not raccoon or dog(he is 26 and has hunted able to tell the difference) He is thinking maybe a coyote or a bobcat. Could a hawk take a full grown duck?
