I don't have a run, and I would like to free range the chickens eventually. Right now my biggest concern is my barn cats. How can introduce the chickens so that the barn cats leave them alone? I'm willing to risk the hawks, and hoping the neighbors dog that comes around once in a blue moon won't kill them all, but I'd hate to turn the chickens loose only to see my barn cats dine on them freely. I have three 12 week old BR and BO 6 bantams and 11 rare mixed breeds that are 9 weeks old. I don't have any wire besides one roll of chicken wire, and I don't have the money to buy wire to build a run at this moment. Thanks for the advice.
