Get an outside dog or find someone that has a dog and collect the dog poo and spread it around your perimeter. We had a fox get 2 chickens and then we got a large breed puppy. My dogs go out occasionally but stay inside most of the time. When we scoop their poo we throw it in the edge of the woods and the fox has not been back in over a year.My property is surrounded by woods on three out of the four sides and we have always had a problem with foxes but this certain fox keeps coming back so I can’t free range my hens. Normally this would be fine but The hens are out around 9 hours each day and because of the Fox they’re now locked in their run all day and they need to stretch their legs and get fresh greens. Also I don’t have enough time to sit out there and watch them. What should I do to get rid of that Fox?
