I really want some partridge brahmas, but I have been able to find any in my price range or area. So I thought I could play with some of the standard colors in my layer flock. Is there a preference to which parent is buff and which is dark? I have a young buff cockerel, a buff pullet and 3 buff pullets with some penciling. I plan to order a few darks and put the dark roo with the buff girls and the dark pullets with the buff roo. But would the next step be breeding the crosses together or breeding back to one of the parents ?
