Sexing young geckos

[DragonRain]

I have a gecko baby that hatched on June 14th.

She (I incubated female) is growing really fast. Last sunday she weighed 19 grams. I haven't weighed her yet this week but she's been gaining an average of 3 - 4 grams or so a week.

I'm trying to sex her (calling her a she until she proves me otherwise), but I've never sexed one so young before. I have her parents here to compare too, and I think she looks female to me. But I'm not 100% sure. I can see very tiny pores, but they are small and look more like my adult female's pores than my adult male's.

How obvious would the pores be on a 20 gram male compared to a female? How obvious would the hemipenis bulges be on a 20 gram male?

I'm just curious. I'm keeping this gecko either way so the sex isn't a huge deal either way. This is my first hatchling

Thanks!

If these help any...

I would say female.

I've noticed the first signs of males tend to be the hemipene bulges. The pores tend to not be pronounced too much until they mature a little more. When they are right on the edge of being able to tell I tend to gently pull the tail backwards and if you can get "her" to squirm a little you'll be able to see if it bulges to the sides (male) or if the bulge stays centered (female). This theory isn't always right but seems to give a better idea.

You could try the wegner method in the link below

Thanks for the replies! I'll try both methods and see what happens, although I guess I'm just going to have to be patient and wait a bit longer to be sure.
