My Japanese bantam hen Koka was killed today... She was laying an egg and then something got her. When I let the hens out at around 4:00 PM to range the yard, and Koka didn't come out. I figured she'd probably just found a bunch of worms in the run and didn't want to come out (our run is pretty big with lots of cover), but then when I went outside to take her out of the tree she likes to roost in she wasn't there. We looked all over until we found her body, in the run. Her head was torn off and missing, her chest ripped open, the egg still sticking out of her tiny body. I would say it was a cat that did it, since it was in the middle of the day and none of my large hens were hurt, but the remains don't look like a cat's work. It looks like a raccoon, but raccoons (from what I've heard) typically kill more than one chicken at a time and she was killed probably in the early afternoon. We live in the suburbs, by the way. What do you think killed her?
