There is a Rhode Island White and those are not it..we raise them as well. I don't see one RIR hen in that picture..those are all red sex links hens and rooster.The one in that picture is how the majority of sex link roos look...sorry.
So..if your going to try to convince people he's a RIR then your going to have to get better "proof" than another RSL roo. You can call him whatever you want...doesn't make it correct and when you breed him to those RIR and sell them I really hope the person buying them is smart enough to know better so they are not un-happy with their mixed breed chickens which are great unless you want RIR chickens because they won't be.
