I've done some digging and looked online to try to verify what I think I already know but wanted to be sure. I can only get sex-link chicks from crossing a gold/red base rooster to white base hens? So for example if I put my RIR rooster on my 3 Cuckoo Marans hens I would get black sex-link chicks? I'd love to have some sex-links, never had any before. So I figure why not breed my own rather than buy. But its not possible to use the Cuckoo Marans roosters on the RIR hens for sex link chicks? They'd just be mixed up colors?
