Im pretty new at the whole chicken thing. So this question may just sound silly to some but I have no clue. I have a flock of 7 girls, 5 Ameracuanas which are all 13 weeks old, a black sex link and an unknown which are 2 years. Tomorrow morning im going to my SIL's place and her friend is giving me a rooster. She said he is about a year and a half old. Im not sure how to introduce him to my girls. I, like im sure most of you, love my girls and don't want to see anything happen to them. I want to do it right. Please imput much appricated! ETA: wrong age.
