Python Egg Incubation Calculator

It depends heavily on species. Ball and Carpet python eggs hatch in around 55–65 days. Burmese python eggs take 60–80 days. Blood python eggs take 70–80 days, and Reticulated python eggs — one of the largest snake species — can take 80–90 days.

Select your species from the calculator above and enter the lay date, since incubation length varies notably across python species.

Most python species incubate well at 88–90°F (31–32°C), though exact humidity and ventilation needs vary somewhat by species and clutch size.

Yes — most python species exhibit maternal brooding, where the female coils tightly around her clutch for the entire incubation period, using muscular contractions ('shivering thermogenesis') to generate a small amount of heat and raise the temperature around the eggs. In captivity, eggs are commonly pulled and moved to an artificial incubator instead.

Once a hatchling pips (cuts the first slit in the shell with its egg tooth), it may take anywhere from 24 to 48 hours — occasionally longer — to fully emerge, sometimes resting partially in the shell in between. This should never be rushed or assisted.

Ball pythons and Carpet pythons have the shortest typical incubation among commonly kept pythons, hatching in as few as 50–57 days under good conditions.

Reticulated pythons have the longest typical incubation among commonly kept pythons, taking up to 90 days — nearly double the incubation time of a ball python.

Pythons are almost universally egg-layers with incubation periods of 50–90 days, while boa constrictors are live-bearers with an internal gestation of 100–120 days before giving birth to live young — a fundamentally different reproductive strategy.
