"Urbanized" foxes have lost a lot of their natural fears and will get very bold. The longer they can come in and kill, and get away with it, the more confident they become. The female I trapped was chasing my chickens right up onto my porch while I was home. She was spending more and more time on the site eating her kill and less time grabbing and running. I tethered a live chicken in a small pet crate and set a leghold trap just inside the door. She went right into the crate to grab the chicken and stepped into the trap. Just as I had planned. So much for claustrophobia. Not such a smart fox after all and one less not so smart fox in the gene pool.
