To me that makes since, I was also wondering because to produce the BSl you mix a RIR roo or a New Hampshire roo with a barred rock. Red over black so I was wondering if I bred her back to a rir would the same princpal apply or would the offspring be 75% RIR and 25% hybrid and show most of the RIR traits. I dunno but I am interested to see how it pans out. Logic tells me that it will be 3/4 RIR and be colored the same or a little darker than a RIR. I currently have 2 RIR hens a BSL hen I am experimenting with I am gonna hatch some of each and compare chicks through adulthood...
