How old to determine sex?

[RA_pierce]

Hi all. I have been trying to find a female for my male Coleonyx variegatus abbotti. He's a healthy adult. I also have a very young juvenile only a few weeks old. So how old must the little one be before I can determine the sex? As of now, no spurs are evident.
Thanks!

I can tell by 3 weeks in most cases. Seen from above, the males have noticeable spurs by that age.

Thanks! I'll double check when it comes out from under the rocks tonight. I'm hoping for a female so I can give breeding a shot.
