TB Fanatic
Ours is raised 3ft off the ground and the tubes that hold it up are pvc.... no rat entry.....One question:
HOW did you keep mice/rats under control?
That was a continuing problem with our chicken-house / pen from the time I was a child.
A raised floor (made out of pallets, especially) would be welcomed by them as our very kindly providing them a wonderful basement apartment....
