It is extremely frustrating when something comes into your yard and takes what is precious to you. In my neighborhood I have stray dogs since their owners don't acknowledge them. My coops are strong and they weren't able to get to my chickens. I did find 2 dogs exhausted trying to dig up my coops but couldn't get to them. A small daisy bb gun is just enough convincing for them not to come back. However, my hen crossed the fence to the neighbor's yard with her 13 chicks and a stray dog came out of no where and caught one of her chicks and took it with her. Now I'm working on my fence since the old one has several gaps where a dog or cat can get into my yard or chicken go into someone's yard.
