I'm not sure if the point is proven yet, but it will be interesting indeed to see if it is. The other thing that will be interesting to see is if the DCXs are sex-linked. I have 5 DCXs, started with 7. Of those 7, half were Del crosses, the other half WR crosses. Now I have 4 that are orange with brown/black markings, and one that looks like a DC (brown/black all over).
It looks like the WRs are 1 cockerel, 1 pullet. The WR/Del crosses are a bit harder to tell at this point, and the DCXs are nearly impossible.
I have a question for you.
When raising meat birds...do you prefer them to be male or female
and
do the boys grow faster?
