But RIR x would not give blue eggs, so that can't be it.I wouldn't have thought of RIR... But this is good. Assuming red crossing with blue gives a coppery color? Thanks! Can't wait to experiment when the time comes.
Plus RIR is red Columbian. That means that the resulting Blue Am x would be red (Mh mahogany) with incomplete blue Columbian. Theoretically.
