Nobody has been able to answer this question. Anyone really know the answer. I know you can use Vowerks but I am looking at what breeds would be used other than this breed. Has anyone tried this? I have a friend that used some Columbian American games that he bred with some black american games and had an off shoot male that looked like a Lakenvelder with white legs. This was by accident though. I may attempt at some point to make them myself but if someone had some information this would help.
