Hello all! I am the first time owner of twelve three week old chicks with a blend of RIR, JG and Brown Leghorns. They are going to be unrestricted free range with about 15 acres to wander around on. I am wondering if it would be a good idea to acquire an older chicken to "show them the ropes". If so, what sex, what breed, how old and where should I get it from? I would really appreciate responses. Thanks!
