Same story here. There’s been a family of fox living in the 1/3 acre overgrown blackberry forest between my property and closest neighbor. They’re super cute and my dog (who’s a rodent slayer) keeps track of them and guards our property, pooping around the perimeter and occasionally charging towards the blackberries growling at anything she sees. She doesn’t go into the blackberries because thorns and prickers everywhere. I’m not sure what she’d do if caught one, likely kill it or battle. My hens free range the property half the year when my gardens are not in season and they occasionally forage at or inside the blackberry border. We’ve had this arrangement now four years. I’ve accepted that I could lose one or more of my hens to the foxes and if I do I’ll get some chicks to replace. Circle of life.
