Thank you for this information and ahparks for starting this thread. We have 21 new chicks today and are trying to sort out what we ended up with since the parents were various combos of RIR and BR. The only ones were not sure about are the ones with the stripes down their backs. Any thoughts?
What is the exact makeup of the parent flock? Also, the black sex link cross will only work for the RIR male over a barred female. It isn't valid for the reverse cross.
