Chameleon Egg Incubation Calculator

It depends heavily on species. Veiled Chameleon eggs take 150–200 days. Panther Chameleon eggs take 240–300 days — among the longest incubation of any commonly kept reptile. Jackson Chameleons are live-bearers and give birth to live young after roughly 5–7 months of internal gestation.

Select your species from the calculator above and enter the lay date (or breeding date for the live-bearing Jackson Chameleon). Each species uses its own average incubation length.

Veiled Chameleon eggs undergo a natural diapause — a period of arrested or drastically slowed development lasting roughly 2 months after laying — before active development resumes and continues to hatch. This mimics the dry season pause the species experiences in its native Yemen habitat, and eggs should not be assumed non-viable just because little visible change occurs early on.

Unlike most reptile eggs, which need warm incubation, chameleon eggs are incubated at cooler temperatures around 68–72°F (20–22°C), closer to room temperature than a heated incubator. Incubating chameleon eggs too warm significantly raises the risk of deformities and early death.

House hatchlings individually in a well-ventilated enclosure with light misting multiple times daily for hydration, and offer appropriately tiny prey (fruit flies or pinhead crickets) dusted with calcium, starting within a day or two of hatching or birth.

Jackson Chameleons are ovoviviparous live-bearers — the female retains developing eggs internally and gives birth to fully formed live young after roughly 5 to 7 months, rather than laying eggs that incubate externally.

Healthy chameleon eggs stay firm and slightly indent when gently pressed, gradually increasing in size as development progresses. Eggs that collapse, turn yellow, or develop mold are typically non-viable and should be removed to avoid affecting neighboring eggs.

At 150–300 days depending on species, chameleons have among the longest incubation periods of any commonly kept reptile — even longer than monitor lizards (165 days) and roughly double a tortoise's typical range.
