Not routinely. We have had one loss to a fox. The hens are in our backyard which is fenced to keep them and our dogs in. It is not meant to keep anything out though it may slow them down. We've only seen one deer in our yard in over 20 years! They're all over this area. We are in a heavily wooded area with trees all around the edges of the propery. We once flew over in a small plane and I was amazed to see that little of our yard was visible from the sky. There are lots of hawks and owls around but so far we've been lucky. We've never had more than 7 hens at a time so maybe we don't attract th predators as much? Don't know. And the smell from the dogs may help discourage them as well. We have three of our own plus a Newfoundland on one side and three German Shepherds on the other. Behind us in forest. Once one of my hens got under the fence on the side with the shepherds and spent a good part of an afternoon hanging out with them. They luckily didn't bother her at all!
