Our chickens are now about six months old, and are (mostly) laying eggs. Their outside space was expanded a few weeks ago to about 50 square feet. After that I noticed that Lucille was bloody on her back, in front of her tail. We thought maybe they needed more room, and added more outside area, probably doubling what they had. Well, today she was bloodied again, so we put a chicken saddle on her. (She looks very cute ) Right now they are loose in the yard and seem so happy. I think THAT is the ideal situation, but I am concerned about the yard. My question is, about how much space do 5 chickens need, to not peck each other to bits, yet to not destroy my yard? We have a large fenced back yard for the dog, probably 1/3 of an acre or so, and that's where their coop is. Any advice?
