Maybe he escaped.
I live in the Greater Sacramento Metroplex. The town of Fair Oaks isn't a town per se, but rather a community of unincorporated Sacramento County. Some years ago, well before my arrival, it was a rural area. The sprawl had not yet spread this far. Now, there are only rural islands scattered throughout the suburbia. This shot was taken in a supermarket parking lot at the intersection of Hazel and Madison, both four-lane (two in each direction) boulevards that are slated to one day be six lane thoroughfares. Once upon a time they were country roads.
This rooster probably wandered away from one of the larger estates that are still resisting sub-division and development. Although they're getting harder and harder to find, there are still homes in the area with horses and other farm animals like chickens wandering about, but they are not so commonplace as they once were. Indeed, rare enough that this chicken practically stopped traffic.
