So we found a chicken mostly eaten with a bit of backbone and feathers still attached. Some innards and possibly the heart left. Found a chicken head. Found another chicken killed but not eaten, just decapitated, head still there Not mauled at all just beheaded. Some feathers from some other chickens left behind. No other chickens seemed to be hurt. What could have done this? Didn't know of any predators so allowed them to sleep in the trees. Didn't have issues last year. Now it's inside every night and a more secure build gonna be taking place!!!
