The inside of our outdoor chicken pen has eroded away because of the chickens scratching in it. There would be no way to grow things in it because they would just scratch it away. I think that at least three inches of soil is gone and the posts may fall if it goes on like this. My thought was to dump lots and lots of organic matter (but what? Don't want wood chips with termites that might hurt the barn (inside of pen is a stall). Anyone?
