Very well said.Birdsitter, you're wrong about no one listening. I get that you and a close neighbor share the ducks, work, food, etc.. I get that they have a safe house to go into as well. I get that someone else near you owns a hunting dog that comes onto the property and maims and kills your shared ducks. My point, and the other's point is this, that dog couldn't have gotten to those ducks if they were in an enclosed area. My ducks and geese are never out free ranging unless I am with them, period. If I can't watch them all the time, they are not let out of their safe pen. It only takes a second for one of their lives to end. Be it a hawk, eagle, or a neighbor's dog. Doesn't matter, if they are out unattended or unfenced, they're lunch for something.
I know you're frustrated because you don't think we are seeing the whole picture. We are and my advice to you and your neighbor is to put up an electric fence if you want them out of their pen. Or one or both of you can commit to being with them all of the time they are loose. I would also be in contact with the person who owns the dog. It obviously hasn't been trained properly if it is tearing at the birds. A trained dog knows better. This person needs to be told there is a problem and that there will be consequences if he doesn't take the proper actions to secure his dog. But even if this dog is finally contained what will it be next time? A coyote? Hawk? Please think about this very carefully.
