Yesterday I walked outside to find one of my pullets decapitated and half-pulled through the chicken pen. Whatever got her couldn't get her out, but managed to kill her all the same. At first I figured it was a neighborhood cat, and the pullet, her name was Mort, was a big for her britches bird. She had no issue sticking her head between the pen bars to peck at things, bigger than her or not and I thought she had done this and a cat got her before she could pull her head back into safety. However, this morning, my bf was talking the puppy for a walk and said there was a falcon literally on the ground in front of the pen, staring at the remaining chicks. I do recall see him hanging out for the last week, but didn't think much of it because the chick pen is fully covered so it wouldn't be able to swoop to carry one off. Anyhow, here's some photos of the aftermath, does this look like a bird of prey attack?
