I have pondered over this for years and now that Im making a new run for the new coop and its decision time. Id like to offer some natural grass for them while providing a safe environment(we have a few dogs and neighbors has dogs). First thought was making it big enough to rotate pastures. This still seems like a good idea but with lots of work re-sowing all year. Right now Im thinking more along the lines of a winter pasture that has gravel/sand to keep them from living on bare dirt/mud and then a summer pasture that is grass along with several salad bars. I really like the salad bar idea someone posted. You build a frame up off the ground with wire over the top as the grass grows up through the top they can eat it but not all the way down to the roots so the grass continues to grow and supply a small amount of grass all summer. Of course this can be sowed with anything from lettuce to spinach or whatever. My thought is that they would go back into the winter pasture in late summer while I try to re-sow some grass for next spring. Any thoughts, suggestions, or ideas?
