when you refer to blind snakes, are you talking about the smallest snake in the world? The skiny shiny black snake? If you are the talking about this species of snake I dont think they need a partner. There Boy/female, I forget the term. So theres no breeding partner. Im not sure on when and how they would go about when they start reproducing. Maybe someone else will chime in and throw some more info at you . All I know is that they need no partner to breed.
