I understand that there is strong demand for the black female. But I could say the very same thing about a bunch of Bwf, rwf and even Hereford females too, IF they are good ones. I assist my customers in marketing their females out of my bulls.  Last year one customer sold the Hereford heifers right off the place privately to a guy. He guaranteed him the same money that the blacks and baldys would bring at the sale. At the sale that week, the baldys brought $30/hd more than the all black heifers.

Jake, using your numbers, if you had 100 cows with 20%  red carriers, only half of those calves would have red calves, so  you would have 10 calves that received a $50 discount, but if you gained  $75/head on the other calves, you would still be $7000 ahead.  100 x $75 =7500 - (10 x$50) = 7000. 

If the baldy calf does so well then IMO there would have to be significant efficiencies in the cowherd too as that is where the benefits of heterosis are supposed to be the largest.
