So I'm getting my very first chickens today! 2 egg laying black sex link hens and a Rhode island red rooster. From what I understand, they shouldn't be bred together, is this correct? Does that mean I need to keep them separate even if I don't intend to breed them together? I do intend to get some 'pure' chicks to raise and eventually breed with the RIR, if that makes any difference. (Total newbie here so please don't laugh at me too much )
