I suspected that would be the answer. My only full size roosters are a Spitzhauben and a Cuckoo Marans. While they both produce nice offspring (so far), I was hoping to do some sex linking. I do have a juvenile RIR that came by accident from feed store. But my other roosters are so mellow and polite and not at all aggressive, I hate to take a chance that the RIR would be. I doubt that my tiny black bantam Cochin would get much done with my barred and cuckoo hens. Makes me laugh just thinking about it
