I want to keep a flock of free range chickens near my house. I have a small shed that I would use as a coop for them to go in and out of but I would like them to free range in the yard. The farm is pretty large so they wouldn't be going any where the shouldn't. I really would like to keep bantams. Any suggestions for breeds that do well free range? I love silkies but I know they wouldn't last a day.
