Ok, I get you. I can see what you mean. If I were to breed for a different color then I would be better off with something like an American Buff since the characteristics are closer to the Sebastopol then an African. Luckily my African has a very small dulap and not such a huge knob, thankfully but it is there. Definitely has a good personality which I like.I think you got the wrong impression...I just meant if you wanted to sell them as "Sebastopols" which was what you originally asked correct? There's nothing wrong with cross breeding geese. I just meant if you wanted to breed and sell sebastopols throwing an African in there might produce traits you or your buyers don't want like the the big knobs, dew laps, big size etc. all of which can skip generations then pop up later.
