There are 18 now, still all healthy and eating. I think I have 13 males and 5 females. Is this a normal male to female ratio in neonates?

It's been my experience that you can't reliably sex Jax until 4-5 months of age. Could you shed some light on your method?
Thanx!

The "males" have pre occular and rostral horns, although very tiny, which are very pointed. Their craniums also look to have a slightly different structure. The five "female" babies have a glaringly obvious absense of these littly "horns" and their sculls look "rounder" This could of course be simply individual anomalies, that is why I was wondering if such a wide variance in the male to female ratio is common.

I dunno, Alan... I would chalk this up to individual differences at this stage of the game, rather than to take that as your qualifier for sexing. I've had females that had 'points' at birth, but have these 'points' never do anything else. And I've had male born with absolutely no trace of horns at birth.
But maybe you're on to something. keep track of your 'males' and 'females', mark them or segregate them into what you think is correct. You might be right...

?

you gave me that idea of putting a tomato in my baby anoles cage and setting the cage outside....mabe they will eat fruit flys off the tomato.

anyways i dont think is a normal ratio i wonder if temprature would change the sex of the babies like turtles and aligators....the diffenent temps make different sexs.(i think it happines in leos to)

I have wondered the same thing. Since Jax have live birth that is less likely because they thermoregulate the eggs in utero so to speak. The mother's personality, behaviour, etc would make a difference in the internal temp she prefers so perhaps some females have more male or more female young. That would be difficult indeed to test without somekind of remote internal chameleon thermometer. Otherwise I wonder if keepers have noticed any given female giving births to disproportionately large numbers of either sex, and if this is consistant. By the way my sexing technique is dubius at best and we will have to waite a couple of months to know for sure. Thank you chamsrcool, as always.
