The rats chewed the Romex electrical wiring in our pole barn. If we did not have a gfci system, it would have burned down. They carried more than a 50# bag worth of pig pellets from the pig trofts up into a box stored on the rafters. The weight of the box filled of feed broke open a roof truss and sagged the roof. We thought it was rotten wood or termites until we went to fix the calapse and it rained down all of the swine pellets like a hail storm.
They chewed some of my chickens feet while they were sleeping, I caught them in the act .
We are at war with the giant rodents. The rain chased them to our dry spots I assume.
