A few nights ago something got into my chicken pen. I heard one of my hens going crazy at about 10:00 so I went out and I didn't see any predator. All the chickens were in the coop except one. There were some feathers on one side of the pen but thats it. None of the chickens got hurt, just some lost feathers. There are no signs of anything digging under the fence at all. Something may have jumped over? Any clue on what it might be?
