We went over this year or so ago. The Brown Red in the SOP APA and the Black copper are genetically different as the Mahogany genes pops into the equasion. The person that was working with the Dark egg thread done a complete workup showing the difference in the two genetically. This is the reason they went into the Sop as Black Copper. They would be Black Breasted not Brown Breasted.This was discussed quite awhile back, and if I recall correctly, brown breasted reds are different genotype from black coppers. I think Don was the one who was discussing it.
