We had an issue with a bird of prey in the summer of 2012. We are not sure what kind of bird but we believe it was a hawk. One day on my way home from getting our son from school I noticed all the birds were inside the coop. Upon further investigation I then noticed one of our female rouen ducks on the ground and had been killed by something. I quickly looked around and saw a very large bird high up in a tree near the creek. I assume this was the culprit. I sent the kids inside and I disposed of the duck. The rouen ducks were my absolute favourite and I was so sad to see one go this way. I began to make more frequent appearances outside and also got a fake Owl to set in a tree in the yard and I moved it around regularly. I saw the bird in the same tree a few times but it never took another bird, thankfully.
