Oh, dear. we're new to chickens, and thought everything was going well, but last night I didn't chase them up into the roosting portion of our A-frame, but let them (6 2-month-old Orpingtons) nest together in our totally-enclosed chicken wire run. This morning, two were missing, with just feet outside by the coop. The must have been *pulled out* and then eaten - but I can't see how they would have fit through the wire? And whatever nabbed 'em had to have very small paws. Possum? Raccoon? Fox? Bobcat? No scratches around the door, no digging (bottom is also wire protected, not that it seems to matter....) We will reinforce with extra layer of offset chicken wire...... Any suggestions??
