I recently moved my ladies from Atlanta, GA to Durham, NC where we noticed a fox prowling around the yard. I understand the general fox precautions, but I wanted to see if anyone else who is renting (i.e. not wanting to invest tons into a permanent structure) has built something that gives their ladies space to roam, but keeps them secure? I'm sure their coop itself is fine, it's raised up and very securely shut. But I want them to free range in an area larger than their run. Thank you for the help!
