Just a warning for those using or considering the palruf plastic roofing panels. We have/had 25 5 week old freedom rangers We had something attack our tractor last night. It tried to dig under but couldnt and then decided to chew on and then pry open the palruf panels where they were sleeping. It ended up killing 2 and wounding 6 leaving all of them where they were. It was strong enough to pull the roofing through the bolts holding it to the tractor and fold a corner big enough to gain entry. I am guessing it was a dog as the carcasses were not eaten and they were left behind.
