The hen in the picture actually looks to be an large old english game hen of a poor wheaton color pattern. I cannot tell but her comb looks to be a pea comb which would indicate some game fowl breeding as well.
There are good Rhode Island Red breeders out there in both bantams and large fowl. The RIR should be very dark mohogany red similar to the posting on the first page of this thread by Brad.
They should have a long, level body which is square in shape making them look like a red brick with a head, feet and tail.
If you are interested in some good RIR's PM me and I'll give you a few names of people to contact. If your nephew is not interested in them they will still make a beautiful addition to your flock and you will know what you have.
Best regards,
Bo Garrett
