Well, I'm sure the BP breeders and the people who know about BP breeding on here would answer any questions you may have. When I had questions about breeding I always got an answer.
Also, there are many different morphs you can breed with your normal to get different morphs besides the normal, but you gotta remember that the weight is very important when wanting to breed, especially for the females. IMO, the weight is the most important thing you want in the female when breeding.
