How does one deter a fox? My mom said she saw one around our run around 7:15, after I left for school, the birds were freaking out, so she let the dog out to chase it. The problem is, how do I keep it from coming back? I need to put an apron of fencing around the run anyways, so it can't dig under.. but what else can I do?! Does peeing around the coop work?
