Heck, I have a couple of "females" right now with question marks on them. When I put males in with them they both went ballistic, heading towards opposite ends of the cage, or one trying to dominate the other. Normally a SURE sign you put two males together. Haven't had time to probe them, and eyeballing is not conclusive.
Truth of the matter is that the only 100 percent certain way to tell if a snake is female is when she lays eggs. Everything else is based on trying to prove the animal is NOT a male, and lacking that evidence it defaults to being a female. In effect, lacking any evidence to the contrary, THIS animal is a female.
Perhaps the evidence just hasn't shown up yet........
