Im a new BP owner and a relatively new snake owner in general. However, I do a lot of research into things I am interested in (guess being in University for 7 yrs has perks). From all this research I have found that when snakes live together, more often than not it is a new owner or a negligent owner. I have not seen a well recognized snake breeder or care taker that does so up to this point. I am not saying they do not exist, but they keep quiet if they do. Take this as you wish.
