When you keep chickens ( or any animals) you have a responsibility to keep them safe. I have gone through several hen areas and each one gets better. Over the last year we did loose two hens to a mink and one to an owl. Each time I rebuilt their home.

They were only three days old when I brought them home. I needed to find a place inside where they could be safe and warm. I also needed to start getting them used to the dogs and the dogs used to them.
