A Backyard Chicken Whisperer's Rookie Mistake

Alright, so I may have accidentally left the door to the chicken run open last night. As a result, one of our chickens got its day started out in the yard at about 4a this morning (when I got up and went outside to find out what all the squawking was about).

This is all that remains. No blood. No carcass. I tracked a few feathers a half a block away before losing the trail. Judging by the crime site, we've concluded that the area Cooper's hawk struck again, this time for the win.  I hadn't blogged about this, but a couple of weeks ago, I witnessed an attempted snatching in broad daylight by a hawk while standing not two feet from a chicken.

Still, what a humiliating mistake.
