i suggest fencing off your yard so your neighbors dogs wont be a problem. if need be clip a wing on each chicken so they dont fly over. putting roses or other thorn type plants all along the fence like bar berry or even rasberry will help keep out racoons but i'm not sure about fox. i only let me chickens out for an hour or so each day when i'm outside but they are still young. after clipping their wings there no way they'll make it over a 4 ft fence so i dont have to worry about the neighbors dogs.
