Anyone use a chicken tractor? I am moving mine around a grassy slope I don't want to mow anymore. I plan to plant lettuce behind it. But now that I have my first chicken-cleared-and-fertilized area I'm not sure what to do. I know the poop is too recent to just plant in, plus the ground is just scratched not tilled. I was thinking I should put down a bit of soil or mulch and cover with black tarp, wait 60 days and then plant the seeds. Anyone throw anything down behind their chicken tractor to later plant in?
