So, after 5 years, my outdoor 25' x 25" fenced in run is a muddy, barren messy. No grass, no nothing, Just dirt. I can't relocate it, but I would like to restore it. I can temporarily make a smaller, adjacent run and direct the chickens into it for the spring, maybe into the summer if needed. I'm wondering what I can do to fix up the run. There's plenty of fertile dirt there, thanks to the chickens! Can I plant it? If so, what should I plant it with? Something that's perennial and fast growing, and tough if possible. Anyone else done this? Thanks!
