last year I built my coop and a run and started with my flock with three hens. This year I have incresaed my flock to thirty chickens and I have built a 300 square foot yard. The run has a top but the yard is wide open. At the start of the summer I was free ranging the flock every day. As soon as the tomatos where ripe all the free ranging had to stop. I wouid loike to pant a wide range of plants in the yard. some for shelter, some for food and a few for looks. I have read a few of the post and I can plant bamboo in the yard. What other plants would be a good idea.
