Crazylilchick, we all try the best we can. I'm sorry about your ducks. Sometimes we make a mistake, or dont anticipate a problem where one could arise. My examples are the handful of birds I lost due to predators---I lost a few birds (one to a dog, and 3 bantams to predators getting at them into or thru the coop). Each time I learned more---I discovered new ways to predator proof. I was so mad at myself, but I felt better after someone told me that the best thing you can do is learn and anticipate based on the bad things that happen. Thats the best you can do. (oh, and enjoy good luck when it happens!)
