a silkie rooster with a RIR/BO? My midwife has a silkie rooster that mates with all of her hens, she doesn't know quite what type they are but they look like a Buff Orpington type and some look darker like a RIR. I guess her duck tries to mate with all of them as well. Anyway, would it just be a cute, weird bird? She has never let them hatch any eggs or anything so this is speculation on my part.
