I have had very good luck with L. Williamsi and have had 15 babies however they were all males, is there some trick to getting females, like temp. or is it just a flip of the coin? I was also wondering if anyone knows where I can get some CB females.

From what I have recently learned the temp you incubate at is directly related to the sex of the hatchling. Meaning the higher the temp the higher the chance of males. What temp are you incubating at?
Please see this from another post regarding the same issue.

I have incubated the eggs at 78 , 82 and 86 degrees and all males, I guess I will try 76 next.

try fluctuating temperatures. Like 75-80s during the day and high 60s low 70s at night. That might help. Interesting to see so many males produced.

Here is another very good link to breeding these little guys that might answer some more questions.

what is your trick for such success?

[wallago]

I keep them in a large exo terra with a Sansevieria plant and some bamboo. They get 18 hours light and temp is kept at around 80 degrees. They are fed 1/8 inch dusted crickets and fruit flies. I also feed them repashy diet and once or twice a month they get peach baby food with calcium. I have four more eggs
at the moment and High hopes that at least one is female. I hatch in the tank so temp and humidity are a little tough to keep constant but I can't argue with the results....except the fact there are no females. This group of eggs I am trying a 60 watt bulb during the daylight cycle and a 40 watt night lite. I am trying the suggestion that I should try changing temps., hopefully it will be the
answer.

Dear Wallago,
I see that's this is an old post.Hopefully you will see it.I've had the same problem.
Everyone has told me that's it's temp.So,I lowered my temps,so far it doesn't look good.
Out of 20 juveniles 10 are male,can't sex the others yet still to small.

I have only seen 2 females out of 60 that I have produced at lower temp incubation I have found does not result in very healthy hatchlings either.

Let me know what you have come up with if your still doing them.If this last batch doen't have any females I will have to conclude that low temps are all bullsnakes and box turtles to say it nicely.

Hi, I'm looking in at the site today for some help with exactly this same problem. I have SEVEN fine, healthy L. williamsi nippers (Sorry, Still Absolutely Delighted about this!!) that hatched at end of November, in December and January. What fun it's been!!
But, All have turned out to be males.
The eggs were laid in the top section of some 4" bamboo that rest in the top rear corner of a 45cm square Exo Terra viv.
The general viv temp is kept at about 77/79 degrees F in the day and ?72/73degrees F in the night, but there's a 4" square heatmat, up in the same top corner of the viv as the 'eggs' bamboo, that is kept on 24/7.
The UV 5.0 lamp is in the 'eggs' corner.
The other piece of bamboo, that rests in the other rear corner of the viv under the incandescent lamp, doesn't get eggs laid in it.
Even though I'm Thrilled to bits with my nippers, I'm really disappointed that there are no females.
I've had two adult males, my Big Blue Boys, waiting patiently for their girlies for over a year, but have been unable to find females to buy for them.. felt sure at least two of my SEVEN nippers would be girls for them.
I've just read an article that Maureen referred to.. about conditioning these geckos when they're WC and incubating eggs. Very interesting.
At the weekend I noticed that the eggs bamboo had slipped down and, therefore, actually away from the little heatmat. I propped it back up again, but wouldn't it be marvellous if the six/eight eggs in the top of the bamboo now, were cooler as a result.. at just the crucial developmental time.
I'll be happy if they even hatch, but, to get girls this time would be Marvellous.
Any helpful suggestions gratefully received.
Thanks.
