After we finish building our chicken tractors and dividing my current flock into them, I'm wanting to divide my 30'x22' garden/chicken yard into 3 sections. Planting a mixed cover crop in one section, keeping chickens in another section, and growing my veggies/keeping ducks in the third section. I plan to then rotate them. I figure the cover crop can grow... then I can unleash the chickens into it. I'm only going to have a roo and maybe 4 hens in it (when I get some Marans next spring, I want to keep them in their own flock). On to my question: What cover crops/grains are good for chickens? I know that clover is loved by just about everything... what else? Also! I'm also getting mixed info on vetch, and I think I have some established in an area of my yard. I had hoped to use that area to tractor my birds over. Is vetch bad for them? Should I avoid that area?
