Help! went down to the chicken coop this am and the pen was destroyed, Posts were pulled out of the ground and the wire was a tangled mess. What ever attacked managed to get one hen out of the coop. (perhaps through the little chicken door on the side) what ever it was actual moved the coop which is resting on wood pallets. what would be big and strong enough to do this and what do i do? the chickens are currently confined to the coop because their pen is ruined.
