When I finished our coop I built a fenced in area of 32' x 64' for the chickens run. We have 11 birds and they have taken the grass down to bare dirt. I am thinking about building on to the run and divide it into 3 sections where I can rotate them between spots and keep the grass in better shape where they don't stay so muddy. Plus they seem to love eating on the grass. My question is, what type grass would be best to plant? I'm thinking something with a clover mix in it. Ideas anyone?
