In the past we have spotted a fox passing in front of our house via our cameras, before we adopt our girls I was wondering if there was any deterents we could use to prevent the fox from trying to get them if he comes back. We live in a fairly urban area with houses close together (we have a fair sized yard though that our dog roams and we will be letting the chickens roam during the day) The fox is only passing to get to the river but I just want to be careful about it if theres any preventative measures I can take
