Is the Buff color a dilute red? What color or pattern can you get if you cross a Buff Orpington X White Rock ? How about if you cross a Buff Rock X White Rock? My Uncle used to cross a RIR rooster onto White Leghorn hens. He got some really good layers and also cockerals that were very good fryers.They where very pretty birds ... white birds with red on their shoulders and sometimes red on the neck.
