Yea the female is just under the right weight. lol
well then she's not quite ready-- and keep in mind that the first season can be REALLY hard on a gecko. I've had some girls who take their first season in stride, and keep weight on, but i've also had girls who lay a few eggs, stop eating and dwindle to 30 grams... with force feedings and constant vigilance, they start eating again...
its always best to wait until they are bulked up beyond the 50g minimum, i prefer 60-70g as a minimum and at least 2 years old.
in the best interest of your geckos, wait
in the best interest of producing healthy, viable offspring, wait...
