they grow rather quickly when they are young. How much are you feeding her a day?
i would also like to add from personal experience, that a healthy diet is a daily feeding and cut down to every other day at 5 months of age. between 12-15 suitable sized crickets a day should be fine until around age 3 months, and then cute down to maybe 8-10 a day. dusting your feeders with plain calcium every feeding and multivitamin and calcium with d3 once-twice depending on the brand of suppliment, natural sunlight and gutloading.Babies grow fast and they need a lot of food. You'll need to start cutting back when she gets to 5 months or so. Overfed females are at risk for larger, more frequent clutches of eggs.
With a normal female veiled I would start cutting back no later than 5 months maybe even soon if she's large. When female veileds are over fed they can start producing a clutch at a very young age which can result in death in many cases. Over feeding can also cause many other health problems in chameleons.Chameleons in my house, isn't 5 months old a bit early to start cutting back every day? My breeder, Kammerflage Kreations, says to start cutting back at like 12 months???? That seems awfully early. Just my opinion. I guess in the end it all works out.
