It happened at night, or so we think. My husband remembers hearing some chicken noises at night, but since they stopped after a few seconds he did not think much of it and thought a brain played a trick on him Until the next day when my 7 year old daughter came home screaming. She found the remains. There was not much of it lots of feathers, wings, feet, all the meat gone. Not far from the coop, maybe three, four feet away. We learned our lesson. It was bond to happen. We live in the populated area, have a small backyard and are surrounded by houses and fairly busy road. For 8 months we were lucky not to encounter predator attack with the coop open, so the chickens could come and go as they please. But I knew the day was coming, especially now with winter weather making animals more desperate. Needless to say, we close the coop for the night now. My daughter is especially devastated. It was our smallest bird a silkie girl named Ruthie. We think it was a fox. What do you think?
