UK area folks probably have the answer to this one - was the red Sussex around before the RIR? The hybrid would not breed true but I am assuming a true red Sussex would?I hatched out the most beautiful red Sussex pullets this spring. I used a Heritage RIR rooster over light sussex hens and of course they were sex link. The girls are now three months old and very pretty red Sussex and the boys look like light Sussex with a little bit more black
har- be sure to come back and post how your girls lay and their personality. Wondering if the RIR amps up their weekly eggs as they say it should and if they are more personable. Was that the reason(s) why you crossed them?
