We came home a couple hours after dark and went to close up the coop. My daughter counted the flock and noticed that one was missing. This girl (easteregger) had gotten into a habbit of jumping the fence, so we got out the flashlights and looked for her, to no avail. I said that hopefully she will be hiding close and will hear the rooster and come back. Well in the morning we ended up finding a pile of feathers and entrails right on the outside of the fence next to the coop. A little later we found the rest of her, headless, about 150ft away. I am pretty sure that an owl got her in the morning because we didn't see the pile of feathers the previous night. Also, a great big hoot/barn owl swooped in and landed in a tree overlooking the area where the chickens are that evening. The hen had just started laying.
