I have yet to get it sexed but I am thinking that it may be a female. I have read Dave Macintosh's sexing technique without probing and going by that I would say she is female. A friend of mine has one from the same clutch and mine appears to be growing at a much faster rate. She is quite big already compared to others I have seen. Another mate of mine has a 2 year old male and I would have to say that she is probably about the same size as his now.
I want to get her probed to be sure, but I only know one person qualified to do probing and he is two hours drive away. Unless I can find someone a little closer I may never know for sure.
