Not worried about the layers too much. They always get shut in their Fort Knox coops at night. The meat birds are just out in their tractor, open and fairly unprotected. However, no sign of the fox today or last night. Lined the edges with wire so he wouldn't want to dig around it and then some wood where I didn't have more wire. I think this fox is fairly domesticated. Our little part of county is right in the middle of a fair sized city.
