It's tough with babies! My best Guess the Sex ever was when a person posted a photo of her snakes mating, and said the fire (or whatever) was the female, and the butter (or whatever) was the male. I replied, are you sure, because from their positions, mating, it would appear that the fire is actually the male! Oh no, she was sure, proven sexes, etc.. I replied, well, just in case, I'd watch the "male" closely in about two months! Sure enough- he laid eggs! So funny.
