The first year or two we lived here, I would see a fox running around the neighborhood in the early dawn hours or on the trail when I was walking. I haven't seen it (them) for a year or so.
The city council just recently passed an ordinance allowing up to five chickens on residential lots. We'll see what happens ... not only in attracting predators, but also introducing a feral chicken population within the city limits. It's bound to happen since the ordinance also bans slaughter. So when they outlive their usefulness, some will most certainy be turned loose. I still want some chickens though. I'd love to collect fresh eggs every day.
Pros and cons to just about everything, it seems.
