So I live in the suburbs on a pretty decent size lot. I let my hens out to free range in my backyard pretty much every day. Sunday before last I had 5 out of my 10 chickens vanish. I walked around the neighborhood and the neighbor behind me told me that they were in his (unfenced) backyard that morning (shortly after I had let them out). The fence separating our properties is horse fence so you can see straight through it easily. I found where they had gotten through the fence but didn't immediately repair it in case they came home, but they never did. a few days later I repaired the fence and again began letting my chickens out to free range. A few days after that (this previous saturday) I had 2 more chickens vanish just before dusk. Since then I have been keeping my remaining 3 chickens penned up. I have seen several hawks around the neighborhood and even saw one sitting on the edge of the run one day a few weeks ago, but I thought that my chickens would be much too big to be prey to them. Am I wrong? Are hawks taking my chickens? Is there any evidence left behind that hawks are getting them? Can they take 5 chickens in 1 day? Are my chickens just stupid and getting lost? I really love having them free range in my backyard. Will I have to keep them penned in their run 24/7 now to avoid more losses? Thanks
